Sure :) We're basicly two founders that have done most of the design and project management of the site. In addition, we've outsourced some design and all of the programming to Ukraine, including the mobile version. The outsourced development itself runs into the 100k's over the stretch of 1.5 years, and in addition, we've done some marketing (40-50k) and had some administrative costs (lawyers, offices, etc.). I don't have an exact sum, but it's anywhere from 190-220k.
Hope you don't mind me being frank, but you got screwed. Perhaps there's some complexity that I'm missing here, but this looks like maybe a 200-hour gig, so at 150 USD/hr (you can get real quality talent for that in the US), you'd be looking at 30k. Maybe more if you wanted to put extra time into the mobile experience, but I doubt you'd need more than 40 extra hours for that. Certainly not 100k worth of work here.
EDIT after reading more comments: looks like I did miss a lot of complexity. Still, it's hard to believe all that stuff was necessary. Need more content? Pay some schmuck $7/hr to make content (or outsource on Mechanical Turk, etc). Or stay extra-lean and do it yourself. Admin area? Probably don't need something terribly advanced. Caching? Not unless you're getting a ton of traffic, which it doesn't sound like you are. Wordpress integration? Doesn't sound terribly useful or relevant, but I could be wrong given that I don't know the target market (if there is one?) very well. Maybe you had tens of support emails a day asking for it - but I doubt it.
