Sorry Thor at only 75 feet you are gonna have a hard time finding someone. I tried to get someone to do my backyard annd the three companies I talked to all wanted at least 100-125 feet to show uo
They would do it but were also gonna charge me something like 400 bucks. I thought that was too steep for something I could do myself (I'm a cheeep bastard) so I bought those retaining wall blocks and stacked them two high. I think it took about 2 hours with the wife helping and cost about 230$
Good luck in your search.
