It can be in B2B. Most people at larger companies have to spend their budgets or risk losing it so you will often see people making any purchases now they project they will need in the next 6 months. Also for small businesses like mine I prepay for my SaaS products and buy any new equipment I need for tax purposes. Make sure that you allow customers to prepay for your product.
Like the others have said if you are really good at it you can make a very good living. A lot of the very successful SEO's aren't the ones speaking at conferences all the time or writing books, why? Because they are busy actually doing SEO or aren't they type that need public recognition to be happy. Just like in anything else you need to be at the top to make good money. In my case I only work with companies in a consulting role instead of doing affiliate marketing because I get more satisfaction in working with other people and being part of their success.
I think you need to add an explanation of the site, the concept, and address how it works. I think most people may be scared away by not having a good understanding of how it works, especially being that it has to do with their personal lives.
...and that it requires giving access to all sorts of Facebook permissions when all the user knows about the site beforehand is "LuckyChat - Connect with someone special"
A general concern that I would have is that there have been various websites over the years that address this problem (the first one I remember was called something like CrushMail back in 1999 or so and the most recent was the pivot made by Breakup Notifier after Facebook shut them down (http://apps.ycombinator.com/item?id=2264660)). But often, they end up being mostly a way for people to spam their friends instead of people getting value out of it. (Typically, they ask you to enter email addresses of who you think has a crush on you. The site then uses that information to notify those people that someone has a crush on them. So when you find a 'match' it could just be that both people entered the others' name on there thinking that they might be the one to have a crush on them.)
I don't think you're really describing business co-founders but instead just the want to be entrepreneurs who are out of work. People who are all talk are everywhere in the workplace and society and of course you will find them in the startup world. No way to get rid of them, so just ignore.
I think the first step is to create a process or set of guidelines for which of these "requests" are worth pursuing. If you can quickly decide if a projects are worth pursuing you will cut down on a lot of wasted emails and only be left with projects that would be a win for your team. After deciding a project is worthwhile I have found that the best way to actually go from a RFP to a client is to develop a relationship with them. Ask for a in person meeting if they are local and if they aren't request a Skype call. Many people respond to you attempting to create that personal relationship and showing that you care about your clients and work. Many people just don't do this anymore and rely too heavily on email, building the offline relationship is still the key to creating new sales opportunities IMO.
I have found that they key is networking with and creating some key alliances. The most important people to create relationships with is your lawyer and accountant. Everyone uses these two professions and if you able to cultivate the right relationship with them they will push a lot of business your way. Also when networking target those who you think will need a service like yours, for example web designers, marketing agencies, etc.
This thread may sound silly, but there's some truth here. Time you spend waiting for the idea is time you waste actually implementing an idea. PMF doesn't happen in your head, it happens when interacting with the market. Get something together, pitch it, refine it, repeat. You'll get there.
I would suggest starting the "idea" with data about paying customers. There's a lot of data out there. Find a market, figure out what they need/want and build a POC. Figure out if your market will pay for it and garner feedback. You might just find that your market will reveal the elusive "idea" for you.
This seems like one of the best "right answers" to the "doesn't scale" problem. You can sell a product over and over. If it's critical to someone's business or well being (according to some definition of well being) then you can sell it OVER and over.
Taxes are a big thing to keep in mind and I can't tell how important it is to speak with a good accountant and lawyer. They will be able to help in how you set your company up, even if you are just one person you'll want to look at all your options like LLC, S-corp, etc. Having the right structure will be able to help save you on the taxes, and make sure you are protected.
