Prosper Loan and United MileagePlus Miles Promotion

Earn 1 mile fore every $1 loaned, up to 35,000 miles; no prepayment penalties either. I was interested in taking out a loan, paying it back the next day and pocketing 35,000 for a negligible interest expense. Then I looked at the fees page and saw a loan origination fee of 2% to 5%. Yikes, I'm not paying 2c to 5c a mile, never mind.
