I'd be too afraid my newbie welds would snap honestly... There are a TON of good shops around where I live and when you do get these things installed is a very good idea to pull your seats so they can pull the carpet back when then do the welding. Better still is to remove the carpet completely which is really not that huge a deal. Then just drive there with 1 seat installed so its easy for them to remove.
Also, if you ever DO diy this sort of thing you MUST do the welding with the suspension fully loaded, IE, no 4 point chassis lifts. Gotta be done on a drive on lift.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
