Building our new ranch house and will be pouring the slab for the skinning rack shortly. Not a complicated project at all and normally would just do myself, just don't have a shop or welder access anymore. Anyone have any ideas of who I should reach out to for a quick job? Basically just need 3 pipes welded together and I'll install the winches.

Ask your local high school ag teacher. They may have a student that would do it.

Academy sells a no weld tripod adapter to build your own.
