Custom utility trailers

I am looking for a very specific utility trailer and it seems I might have to get something custom built to get exactly what I want.

I’m looking for a 7x18’ utility trailer with side loading ramps not a side gate. I would also like the rear gate to be 2’-3’ with a dove tail.

Since this trailer would be left outside I am thinking of going with a powder coating instead of paint. I also would like it to be gray or tan and not the typical black color.

I have looked online but haven’t seen many that match my specs that are not large equipment carriers. I am looking for something with a 7k lb range not 10k lb to keep the costs down some.

I’m in the Houma area if someone can recommend a custom builder or knows of something that fits those specs from the bigger names. I’ve looked at load trail, big Tex, Goliath, diamond C and top hat.
