You need to be careful with larger diameter wheels with a nearly stock ride height. Anything larger than 17's start looking goofy. You need to build the vehicle to accomodate larger wheels, not just bolt em on.
Your best bet will be to stick with 17" or smaller wheels, but get taller tires to fill the wheelwells up. For example, with 17" rims, 255/60/17 or 275/60/17 tires will look better than 50 series tires. If you went with 15" wheels, you could get. say a 255/70/15 tire, that would fill the fenders up nicely, or possibly go with a 275/60/15.
The problem I see in your case is the $1000.00 limit. The bigger the wheel diameter, the larger the bill to go with them. I've spent the last year or so looking at wheels myself and haven't really found exactly what I'm wanting either. My budget also dictates this as well. I've found lots of wheels I like, I just can't afford them right now.
Since you asked though, I'd be willing to part with these wheels/tires for $1000.
