Summer 2015- Quest for money

I'm wanting to leave my job at Tesco. Although I've been making money through commissions, I need more to live off of, so I've been trying to build up my online presence on different websites like Etsy. I found a site called Fiverr where you can offer a service and be paid £5 for it. Although £5 isn't a lot, I think that it might be possible to get quite a few quick commissions out of it.
