You tell me what you want, I assign you an angel (or myself) as your signatory and the deal is done.

Some requests might not be feasible, and I may counteroffer.

Mainly, souls I purchase qualify as heathens, which may alleviate some of the burdens of your mark or possibly remove it entirely.

There are no guarantees regarding a specifics, as all is relative. The closer you get to what you want, the more significant the agreement. The farther from, the more "slack" you'll have, making for a win-win.
