Youth Hostels are the way to go...you typically spend about $10-15 a night and that usually includes a breakfast of musuli, breads and jam. Stay out of the UK its expensive...unless you want to hit up Edinburgh International Festival...cause thats pretty sweet. Also, don't overpack...you don't want to lug too much stuff. Besides you are probably going to pick up alot of shit on the way. You could always work at a resort...I'd recommend
www.thepinkpalace.com in Corfu, Greece. It is quite the awesome place and you can extend your trip. I traveled around for about 2 months and spent about $3000. Now just go DO IT!
