I started doing my own 1911 trigger work from watching YouTube vids, bought an Ed Brown sear jig, some Arkansas stones and brass punches from Brownell's for about $80. W.C. Wollf springs, sear and main springs and got busy on some of my 1911s. I have a SIG RCS CCO sized 1911, it took virtually no stoning, smooth as a babies butt, just adjusted the sear spring tension on the sear and disconnector. First try, no creep, clean break at 2.2#s, toooo light for a carry piece, about 30 min later (the series 80 style levers are a pain to reassemble) and I have a 3# trigger. What can go wrong, ruined sear, hammer, sear spring, all can be replaced. If you are not comfortable completely disassembling your pistol then this is probably not a good idea. Cost of having someone skilled doing the work $150-200. Usually carry my RCS in an old Galco pancake hoster for a SIG P239, while on my belt it holds the pistol very securely, but when you take it off the pistol fits very loose. With the SIG slide it doesn't fit the average 1911 holster.
