I've raised £2000 to get two friends off the streets and into work

I recently came across a friend sleeping rough outside Charing Cross station. He and his buddy had lost their jobs and then their accomodation, forcing them to sleep in a shelter in Embankment Gardens.
Both guys are trying to get jobs, one having been offered a job, but needing an address to secure it.
Having investigated what it would take to get these guys accomodation for a couple of months, it would appear that if we can raise £2000 - £2500, we can get them secure accomodation and some new work clothes. The housing provider will give a reduced rate on rent until they secure work.
It would be terrific to raise this money and get two guys off the streets this side of Christmas.
Please help if you can, it would be greatly appreciated.
