I went on a site where you post projects for programming projects, and people bid on them. I recieved a bid of $600 for the following project: 1) Custom vbulletin design 2) Custom site design to match the vbulletin design, so the content part of the site is integrated with vbulletin 3) Logo design included 4) Photo gallery 5) Video gallery 6) Store locator 7) Product review database This is all for the same site. So basically, the entire thing. Is this worth $600? Thanks.
I think if you break it down into small projects you will loose time, i would stay with one design firm if i were you. Yeah, you might pay a little extra but at least you will have it done right.
