General rule of thumb: Make sure you get your new job before you quit the current one. I know this doesn't apply for you today, but it will.
I'm not sure what Wales is like as far as how the house address numbers are posted at the street, but here in 'merica, house addresses are spraypainted on the curb uniformly so that emergency & police can be more efficient.
Anyhoo, my point is, if Wales falls into that category, go get some paint & stencil at the hardware store & go to the neighborhoods that both need refreshing & have residents with enough disposable income to pay you.
Do it right & you can get through college without mucking about in a real job.
