Help locating a boat for my needs

Hello

I am new here and hoping that some of the veterans might be able to give me some guidance to finding a manufacturer/builder for the boat I would like.

Here is what I would ideally like:

Size: length: 25-32 feet Beam no greater than 8'6" trailerable

style: tender/launch style or something patrol style similar to Mitchell 22

Power plant: diesel...yanmar cummins etc. ideally decent HP 200+

Drive: Tri-Max surface drive, Hamilton water-jet, V-Drive

Hull Design: planing or semi-planing good sea manners and decent speed.

I have found some in the styles I have listed but none with diesel and surface drives or Jet drive my ideal combination.

Any help toward a brand/builder etc. would be greatly appreciated.

Thanks

ps. Would definitely consider ex-military etc. boats

ps. price is an issue, so nothing crazy off the wall please
