I would like to open a sort of “memorial park” in my community?

but this takes money I don’t currently have. This memorial park is different than a regular cemetery. It would be like one in I think it is South Carolina and the people buried there are not embalmed, do not have a vault, and do not have to pay a fortune to be buried. It would be in a park like setting with small markers and they can go back to the earth naturally.
What is the best way to do this? I don’t have the best credit since I had 3 surgeries in 5 years. Any suggestions?
