Best of luck in your new ventures Nick, I have a feeling you'll do just fine.
As for the part time work, there's always plenty of jobs around.
Out of my 32 years on the Fire Dept. I spent 25 of them working on my days off, as do most firemen.
Most of the time I was driving trucks but other than that I did everything from driving cabs, to painting houses to cleaning offices.
Lotsa work around for anyone who wants it.
Go get 'em.
