I am looking for various options for cooperation, assistance in purchasing equipment or renting equipment.

But all the types of cooperation you are looking for have in common that you need money to invest in equipment. So it's not about various, you're looking for an investor.
You have already received an answer that it will be very difficult because there is a very high risk for the investor. You can probably expect only some advice on which equipment to buy and who are reliable equipment sellers. It's the closest to co-op you can expect.
