where can i post a $50 contest?

i need a landing page design made... its very simple

can someone tell me where to post it?

I am afraid that we cannot accept a contest with such a low prize.

Depending on how much material will be on the page, it would be a good idea to add a 1 or a 2 in front of that price if you want to attract good designers, which is the only way to go with a landing page. If you're not careful about who works on this project, you may get no effect or possibly even the opposite effect.
