I don't agree with those calculations above, because the quality would be lower if someone try to make proper thumb and description in few seconds
But I don't mind spending more time on it in order to do the job properly.
I'm very interested in this job offer anyway. Its the best if you can tell me how much you can offer on my e-mail: webmaster [at] designfuck [dot] com OR Ecchi22 [at] gmail
Because I'm in rush now, I'll send you an e-mail later. I'm pretty flexible about payment rate, but I don't wanna work very cheap too.
Cheers~
