I would think you could contact any of the KY-wide houseboat companies and ask them for some leads. Heck, I bet they'd even be able to build you or quote one to be installed.
2 of my slip neighbors had new party-top biminies installed. I believe they paid $7.5K. They're in Nashville, so I'll ask to see if I can get the name / number for you.

My 10 X 14 top only cost me about $300 ----- several lengths of SS20 fence pipe, a dozen or so Speed fittings from TEK Supply, a $35 tarp, and some bungee ball tie-downs. Looks good, works great, easy to take down in winter.

Well, I spoke to my neighbor over the weekend and he thought that his bimini set up actually cost him ~$5K. The person who did it is located in KY near the Cumberland somewhere. It's the same guy that did the work for Sumerset when they were in business still. I gotta say, his top sure look nice. He even put two panels so that my neighbor can install ceiling fans in it. Looks very "Sharpe". Hehe. If you're interested, let me know and I'll get the guy's name. Jon didn't have his contact info on his boat, but at his house.

I had a place called Aluminum Houseboat Products in Kentucky build me a shade structure for my HB and ship it to Nevada for me. I don't know if he is in business anymore, because I can't find his website anymore. He did good work for a reasonable price.
