Skippering work will need to be commercially endorsed. You can commercially endorse your PB2 but it limits you to so close to land and by day only that it’s not a lot of use for commercial work.
I’d look to do your Advanced, and commercially endorse that. You’ll need your VHF Short Range Certificate, an approved first aid ticket, a medical (ENG1 usually though it’s possible to use an ML5 for inshore stuff), PPR course (done online) and a sea survival course (I recommend STCW rather than RYA as if you find a job needing all the STCW basics you’ve already ticked one off).
If you’re going to try and make a career of it it wouldn’t be a bad plan to start with your medical, no point in throwing thousands into qualifications if it turns out you can’t pass an ENG1.
In terms of work there’s all sorts, safety boat work is regular if a touch monotonous, pleasure trips if you’re somewhere scenic, things like pilot boat coxswain (although they usually prefer Yachtmaster Offshore or even Master 200 GRT) etc.
Good luck in your new career.
