Need help getting half decent career?

I don't have a decent career, just a little temporary job at irving tissue stacking various tissue paper on palettes for the forklift driver's. I need more of a career than like 65 cents above minimum wage. I do work 12 hours a day, between 4-5 days a week, depending since my schedule varies. my only problem is my only education is a forklift safety classroom instruction certificate(I never even touched a forklift, it is just a one day course to help you learn the basics of working with forklifts and forklift drivers) and a high school diploma. my job history is maintenance/cleaning at a sports facility, where I cleaned, got fields ready for various sports and activities, including soccer, indoor paintball, mixed martial arts events, and a few others that required next to no preparation and I have been doing that on-call since 2007, with a brief 5 month stint of doing it part-time. I have also worked at a golf course for 6 weeks full time in 2009 and 8 weeks part time in 2010, where I cleaned golf clubs, power carts, stored them away(for the members who chose to have storage), assisted the golfers getting ready for there round of golf, and help them after there round of golf and getting range buckets ready for the driving range, as well as washing the golf balls after they have been used. Then I just have the little warehouse experience, but I can't do it forever, since I have a dust allergy, I have a bad back, causing severe pain in my legs and arms, and I will need more money soon. I only have been there a few weeks though, but there is no way of getting promoted anytime soon since I came in from an agency, so it is 18 months if I quit before I can go work with irving tissue (or majesta) and its another 18 months with them before I can get more money. so its too long, I do like to work with computer hardware and I can type at 30 words per minute, but that's it. any help is appreciated, thanks. I live in moncton, new-brunswick, canada, so a decent job would have to be 550$ a week, which is about 12$/hour
