I'm just trying to focus on more income at this point then trying to cut back money.
Ok, let's talk about that.
First, ask for a raise! Worst your employer can do is say no. Since you've been there 3 years at minimum you could ask for a cost of living increase and justify it by inflation. Over the last 3 years CPI inflation has been over 5% http://www.bls.gov/cpi/
so there is justification for asking for a 5% raise.
Honestly, most of the people I know who have taken part time jobs have been in retail in some form or another. Then there's always food service.
Some other options:
1) valet at a fancy restaurant/casino
2) bartender (but you'd need some training)
3) data entry
4) hotel worker (front desk)
5) dental hygienist assistant
6) life guard
7) research assistant
phlebotomist (need a certificate)
9) gas station attendant
hmm, i know there have been articles about different side jobs before on this site. Maybe search GRS history for other ideas.
You might not even need a 2nd employer. Any skills you can monetize? Tree trimming, pool cleaning, dog walking, sewing, etc.
