Wanted - Plumber ASAP

Looking to hire a plumber to come by and check my basement. It has been water proofed but the problem is there is a small hole in lower wall where water was coming in, other side of room had black slug on floor and sump pump may not be working properly. Very strong odor. If u r a experienced plumber and would be willing to come by and take a look and see

if its something u could possibly fix, please reply. PLEASE no handyman looking to make a buck with no idea about

possible solutions. My cellar is a mess - all my things are in safe area - not that they were in danger of damage BUT just moved to see what I had as far as what was going on. I had someone come by and snake out a line a week ago and about 7 days later, somehow black slug come on the floor from WHERE So there are a few issues and I need someone with experience - Maybe wall just needs a patch - easily can be seen where slight hole is but need to find out why I got backup with slug and where and of course the oDOR (Appears to be from sump pump?) and that's a guess. If interested, please reply. Have called plumbers but most do not reply and one wanted $165.00 just to drive from Watertown to Torrington to take a look. NICE GIG. Can call 8606183816 in Torrington (Joe)
