Hi,
I had to bid over $700 but I am actually offering only design services on this one. I do not believe in "jack of all trades" on such big projects, so either you will have luck to find some reliable agency here or decide to hire two people, designer and developer separately.
I can do photoshop mockup and code it into CSS/HTML for 330 USD.
I was wondering if there is any ready-made script that you would like to use. If you have anything in mind then I can integrate new design for you.
Also if you find a good programmer I am happy to collaborate.
Best regards,
Nina
