Lol. I find it funnyhow you refer to other currency as normal. Is bitcoin not normal to you? Anyway, I don't think there are any sites that offers lending with paypal. Perfect money has a lending option in their site tho I don't know if that actually works.
Also you really need to be 18 an older to get a loan. It's illegal to get loans if you are underage plus how will you evwn pay if you are underage. If you are underage and want to get loan, your best choice ia the forums' lending section. You can ask people here to lend you paypal, just provide a valid collateral.
For lending sites:
Try btcjam, loanbase, btcpop, bitbond.
Even for this Bitcoin lending sites he has to provide some personal documents that have to be verified and some proof of income so I don't think that he can get a loan.
