Thank you for your question.
In this environment, credit worthiness has been what they say "tightened down". So unless you have security or collateral for such a loan, it is unlikely you will get one.
The following loan agency are what are called peer to peer lending agencies. They can provide reasonable interest loans and the credit worthiness criteria is not as stringent. This is because of how the loans are funded.
Individuals like you and me, bid down the interest for the opportunity to lending to you and you accept the winning bid. You do get an opportunity to not accept the loan terms. Downside: you may not be able to borrow the full 25,000. http://www.zopa.com/
Peer to peer: the same as zopa, but for the time, your loans are bid by loan partners. The site is going through a registration process so no lenders are not accepted; but they are still taking borrowers. http://www.prosper.com/
Finally: if you had relatives or friends in your network....as many as it would take, who were willing to make the loan. Then they may be willing if they could guarantee that there was going to be over site and a way to ensure the loan would be paid. Loans between friends and relatives can create problems BUT you and them can register with the following company. As long as you have enough friends, relatives and network to make the loan, the following company will write the loan and manage it.
