Paying debt through slavery (quest request)

[Encon4]

A situation where, the PC gets a loan in riften from a "legal" Bank Black-Brian the deal looks good, asking a loan of 5000 gold is a good way to start gearing up and hoping to pay after adventuring for treasures, but after a week some colectors appeared to pay back 150.000 gold, outraged the PC asked why such high pay interest of 3000% then they said its in the contract of the deal, the paper did show in the end that is correct, but it didn't show during the signature, it seems that it was enchanted for the letters to be invisible.

Everything was legal and there's no way to proof the authoraties about the scam.

The collectors forced her to pay every gold she got incluiding all the items that could cover the debt but is still not enough, for now the let her go, but each week it will pass will double the debt, and knowing that is impossible to pay the debt in time and risk it to pay 300.000 and after that to 600.000 and to 1200.000 gold, means she could get an infinite spiral of debt.

completely broken and naked, she decided to go back to the bank and reveal that she has no possibility to pay the debt on her own, so she was offered another contract, that the debt will freeze meaning that will not double and will be paid if the Pc agrees to volunteer to become a slave to the shareholders, these shareholders are rich people that can put her to work to the mines, farms, pushing carts, being a maid, being a concubine, a slave prostitute, everything fitting for a slave, she has to sign that she will have no rights as citizen and she has to work as a slave for the rest of her live and it can be inherited to the descendents that debt, or pay her through her own gains. She will won't use any chains because she's a volunteer, but escaping from her responsabilities will reactivate the debt and accumulate more. the only way to gain money to pay the debt would be to be willing to do dirty jobs that even for slaves which they rather be punished that doing it, the shareholders will pay money if the pc, will mate with beasts with public, smuggling drugs, being tortured for fun, doing sewer races with beggars and skooma addicts, fighting in the arena(more like being a punching bag) and so on. every money she gets will disappear in her inventory since it will be automatically pay the debt.
