Generator upgrades

Hello Everyone, Due to my age and health condition I would like to automate my generator. I would like 12 volt electric start, automatic transfer switch, exerciser, and propane conversion kit. Between my son in law and myself I feel we can complete these upgrades at home instead of going to a shop. Any and all directions, suggestions, recommendation, drawings, etc. to accomplish this is greatly appreciated. Below is the dope on the generator.

Thanks Wilber, Being from the mid south we deal with heat more than cold like you guys. I am building a building without wood and a top only. It is semi closed in on the sides we receive rain from and I also am going to add a fan to assist with cooling. Our local propane supplier won't allow a regulator inside so it will be located outside of the gen shack, and yes there will be a cutoff valve at and downstream of the regular. He also requires high pressure to the gen although its only 25 ft from a 320 gal tank, but in his defense the pipe will continue on for 100 ft to heat my house (another $60 regulator) I wish I could find someone that has added electric start, just wonder how much trouble and expense it is. I suppose 1 step at a time first convert to propane. I wonder which one is the best and less trouble to install and most reliable? Thanks for the reply.

The reg will be 3-4 away from gen. The gen shack will be nothing but a metal floor, studs and roof (fireproof) no wood. It will be positioned about 2 ft from 2 metal storage blds one west and one south with about 2 ft over lap. This will prevent rain from getting to the gen on the 2 sides that 99.9% of our rain comes from. Without the walls the heat can escape easily, the fan is for when it's running and the OSA temp is 95 + and not uncommon to be 100 ambient, Heat index up to 115 or so.
