How much should it cost me to find out what is pulling juice from my battery ? on 1996 Chevrolet Blazer

I have a 1996 Chevy blazer and my battery always runs down over night. I have to disconnect battery after driving so I know it will start next day. How much should it cost me to have a shop figure out what is pulling juice from my battery ? ( Electrical check )

Any add on equipment? Are any lights staying on dome,glove box under hood
map, under rear view mirror inside? Fueses can be pulled one at a time with
positive batt. cable unhooked with 12V test light hooked between batt. post
and to unhooked cable. With everything off and doors closed light should not
come on at least very bright. Get inside with doors closed and everything off
start pulling fuses one at a time, then put fuse back,until light goes out or dims.
Have someone help to look at light and say when it changes.Sounds like a lot
of work but that's how YOU can find your drain. Or just get a shop to do it.
