Even whith signed msg which prove that your account is yours and i am happy to see that that you are actually the owner, i beleive that your requesting loan is to hight without a collateral even with your trust/rate, all the risk goes to lender..in my opinion every purchace can be wait for 7 days instead of paying 0.15BTC more but this is your choice...anyway i beleive that you may found someone to help you, good luck!

Kind Regards,
