Sure, if you are not going to do your own covers (which I have done - check them out on my publishing page), you can try and get an intern or undergrad to do one at your local college. I'm sure a budding graphic design person would love to get the chance to make a book cover.
Hi,
if you want custom covers for a low price go to guru.com they hire people on the price that you can afford and conditions, always own your own covers, get it in writing
You have to contact Marcello Milteer (on this network). He's the author of Karate Cat. He did my cover for my next book. He is great, reasonable and a pleasure to work with.
