Hi Tadfisher. That puts it in more perspective. NS really has no incentive to make my site shine and, even worse, if the site blows up they might, as you say, take it hostage. I think I'm going to cancel the service before they begin the website. Honestly what really sucked me in was this sales guy on the phone telling me that the best idea for me at my stage while seeking funds is to get the site up so that venture capitalists and angels can find it easier. He made it sound like if I used their service, they would help me find investors. After talking with the consultant, I think that sales guy was just full of shit (as most sales guys are) and was just telling me what he knew I wanted to hear in order to sell his service.
I myself am not a developer, though I'm not entirely ignorant of the technical side. I have developed my idea single-handedly through much trial and error and just want to steer my idea to fruition. I already have the entire blueprint for my site, but I just can't build it myself. What I really need is a service that will build the site, even if they take a stake in the company, like Y Combinator.
And no, I'm not the type of person Ashton Kutcher hates (Mark Zuckerberg wannabes). I seriously have a fully-baked idea that began with the question, what does the world really need. Is Y Combinator my only viable option in your opinion?
