I need a more powerful pro forma template that includes both rentals and condo sales in a ground up development.

Like the title says, I need pro forma help. My templates I have are simply not versatile enough. I'm working on a land assembly with multiple owners, each one wants to do different things with their land, such as get an annuity, sell out right, buy a site condo at the end, or put their land in as equity. Combine that with partners that want to have both surface parking and underground parking, as well as rentals they hold onto and condos they build and sell. All together, I don't even know where to start to find a template that includes all of this stuff. Any ideas?
