A plumber to Sweat in new hose bib and T off i utility sink?

[fitz19d]

Miracle fil may be too busy to help within the schedule i was hoping for. Anyone know anyone that isn't a fortune to put in a utility sink in my basement , Td off my house bib right above house supply rather than messing with the brittle looking plastic pipe i have?

Have a sewer cap i was just going to p trap and run into, maybe a back flow valve? And probably snub my nose at code and trying to run vent from basement to roof. Sink will have regular low flow so I'm sure i won't see the p trap evaporate.
