If your old enough get a good job (hard to find theese days) If you can't find some street jobs and I mean 24/7 street jobs and hard ones that take many hours my other idea is have an garage sale of expensive stuff or jusst stuff you don't need (by the way for a garage sale depending on some terms of states and cities you may need a license permit for it)
Get a job which pays $10/ hour, and work about 50 hours.
Work for a few days.
