It depends on the material to be cut but try in Lowe's, most likely they will be able to do it
Yes, Lowe's has cut-to-measure service on wood products.
You can rent their tools
You might be able to DIY, usually they offer you saw and table to do that, but not usually for wood sheets, it's more for boards.
Think they will only cut sheets of plywood and some lengthy boards. But not miter or a bunch for different sizes. That's even if you can find someone to assist.
