If you have sufficient collateral that can be placed in escrow during the loan time, you probably don't need to bleed yourself with such high rates. 
I don't have a lot, thats the problem :/ but I am willing to work with people both on that, and verification.
How do you plan paying an extra $750 USD in 2 weeks? along witht he rest of the 4.5 BTC, which is almost $3400? How much of your own money will you invest in this mining rig? If it's less than the loan amount, well, I got bad hopes for you. Especially when you don't have a collateral.
Thanks for your "bad hopes" - So how will I pay 5.5 coin in 2 weeks? Because, if you read the thread, I have 5.5 BTC already paid for and arriving next week, which is when the loan will be re-paid. I am looking for the 4.5 now so I can complete my sale now, instead of waiting until my already paid for BTC arrives next week.
Thanks
