Are you talking trap, or other stuff?
Given your parameters, for trap, it is going to be hard to beat an older BT99, Lloyd. Hell, there are take-off stocks for sale for the things on the sites, that could be whittled to a bit closer to your dimensions. Seems like 1-2K would get you to look like a regular on any club field, not cheap, but, cheaper than most anything else.

Good luck.

Best,
Ted
