I've shot about 500 weddings and could not afford the time to develop and proof them. I printed all the final prints in both B&W and in color but developing is too much of a time waster.
I agree with glbeas, find a great lab and clearly mark everything.
You'll burn out if you start processing all this stuff yourself. Part of this job is farming out stuff that can be done cheaper (time wise) and concentrating on the part that needs high quality.
I used the same lab for 9 years for developing and never once had a problem although we've all heard horror stories. (like when someone stole the pickup drivers car on a Saturday and 60 weddings were lost.)
My two cents,
