Creative strategies for new construction for Short term rental in vacation hotspot!

I am a founder of a steel modular prefab design, engg and mfg startup. I am planning to build my model home in a vacation hotspot on a lakefront real estate (that I own free and clear) with 150' lake frontage and dock rights with potential for short term rental at 50% occupancy at a rate of around 500/night. A post construction value of more than 750k with 250k needed for construction. Lot value 350k. Looking for investors, lenders and construction partners that can finance, invest or be a build partner (GC). The terms are flexible as well as lucrative and will strive for a win-win situation. Would like to know all options and strategies available for this.
