The company I'm working with has over 100 domain names ready to go but the thing is we need someone to design a basic template for those websites. Now I already have 1 freelancer that I'm working with, and he charges $80 per website done.
If you are willing to be paid $80 per website (Wordpress back-end, no need for content, same template every 5 websites, just different header image/color theme) then I'd like to invite you to the team. If your initial work is good enough, then you'll be guaranteed to have at least 50 other websites to be finished - that's easily 50x80 = $4000.
Also if you can work faster than the other freelancer, then basically you will get more websites to be done = more money :)
I hope I made myself clear with the description above, if you have any questions, feel free to ask away!
