Masonry, concrete

I need a block fence built at my commercial shop. It’s roughly 50 feet long and I’d like to go 8 feet tall. I’m not interested in hiring a contractor who’s just going to sub it out. I’d rather pay the guy directly who’s actually building it. I’ll buy all the materials we’ll need and pay you cash when the job is completed. I also need concrete work done too and building an awning as well so there’s plenty of things to do if you have the skill. Pay depends on skill, absolutely no money will be given up front. I’m cool with after hours or weekends if you already have a full time job
