How many quotes have you received? What is your budget?
As far as a budget goes, I'm not sure really. I understand that you get what you pay for and I also understand what it's like working as a freelancer, so I'm not trying to lowball anyone.
I mean, for a down and dirty idea of what I'm looking for is basically pcpartpicker.com but definitely not a clone and clearly a different industry. I saw this site the other day and it has a lot of things that I have written down for features of what I want.
Anyways, I just feel like I've been talking about this site idea for over a year and have yet to really find anything that's better than what I came up with and figure it's time to just get it out.
I'll mail you back my take on the offer -- if it's turning someone off to responding to you, I'll respond as to why. If it looks perfectly reasonable, I'll let you know that as well.
I will also respond with a quote as to what I think it should cost, in terms of hours and dollars.
