backpack through europe. 15 countries, 45 days (100% sureness and NO TIME LIMIT) - Group Travel

i'm currently planning on backpacking trip through europe with a low budget and it will start from London. actually this my first backpack trip to europe, that's why i'm looking for travel buddies too =)
i can sleep in station or airport to lower the costs, actually i'm a very flexible person. i can eat anything, raw,cooked,processed, or even a frozen food!
my preference to go is spring, because Travel with a backpack and moving between places would be more easy in a good sunny weather.

the activities:
-rent a vespa in florence and drive it around
-cycling
-vintage markets
-relaxing in santorini!
-drink beer in Germany
-watch roskilde festival(denmark) and glastonbury

no time limit and if i should work during the trip to earn money in order to continue the trip, is not a problem =)
just message me if you're interested and we can discuss it. i'm very open with other suggestion.
