There are a lots of goods and services in the marketing section. You can look there. I think the best way is to do small projects. If not there's always the sig campaign.
You can also try some affiliate programmes. For example on www.onehash.com you can earn some profits for convincing people to betting. You got profi only for first bet so you can try to create some network with your frineds or trustworthy colleagues. Works with mine.
Goodluck
