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

I can swing by and show you how to sweat that in real fast if you want

I think the biggest thing now is, I'm not sure how he was meaning to also split it off to the sink, at least with what he had me buy. (Sillcock, length of pipe, bunch of elbos, but no T, unsure if my main supply into the house to the sillcock but before the plastic had a cap to open or something)
