If you want to have professional work done for a minimum price you need to checkout
getafreelancer
I let all my stuff done by freelancers. They are as professional as the designers you find here, but you pay a huge lot less money. They work for 3$/hour or sometimes even less and make a work that is not a bit worse than of the designers you find here. There most people come from poor countries, which doesn't mean that their work sucks. You find people for every work you can't or don't want to do yourself. And the best is, that you can pay after you have seen the work!! I let all my design work done by freelancers. If you know that place you will never go anywhere else again
