I would contact a number of local builders and get an estimate for the cost of construction for each elevation and plan.
As an investor and broker in Florida I would be interested to review your designs and open for joint venture once you did your homework.
Advertising your product to local investors and realtors can be effective as long as your designs meet todays real estate challenges.
Building "green" is where it's at now and custom. There is also a growing need for 1 level homes for the growing aged population moving into their dream home. That's creating a niche! -The Jewel of The Rock, Prudential 503-936-2432
Good luck. If you need help contacting the right person there, feel free to contact me.

He started marketing to a handful of local builders and Realtors. That built an audience and trust. After that he grew and grew.
Now there is not much market as nobody is building. There will be an opportunity however and when that time comes we will need good talent in design. There is always the need for a fresh perspective.
I would be happy to speak by phone in the coming days and will share my 25 years of experience with you.
