THAT is a good way to run such a contest!

It’s a good prize, but only one person wins it, while everyone else just essentially drew free art for you and got nothing in return.

The way ZippySqrl suggested sounds like the best way - everyone who enters gets something in return, so they’re not wasting their time.
Otherwise, about the only way you can do it without compensating everyone is to have an extremely generic theme/subject - no “draw this specific OC/character/ship/fetish/whatever” or anything of that. The theme would have to be something that can produce images that are enjoyable to everyone. And even then I wouldn’t expect too many responses, since people would rather be creating art that either they want to create, or that they can profit off of.
