That's the exact same crate we had for Kito (a smaller size though).
He didn't mind going in it, and even slept in there at first, but once we came home and he was limping--the silly goof had gotten his paw stuck in it

Anyway, just make sure Casey sees it as a great place to be--treats work wonders to get them in there, you could also try feeding him in there too. Give him a few toys when he is in there, so he doesn't get bored--I recommend that Kong--I know you said you are short on funds, but they are an awesome toy. You can fill them with treats, peanut butter, canned food, kibble, oatmeal, cottage cheese, ANYTHING Casey likes--mine will even eat ice cubes out of them. You can check their website for recipes or ideas for stuffing them. It will keep him busy for a while--once or twice a week, ours have to be alone longer than usual, and that's what I give them.

Good luck!!!
