Binding pledge Character

I really like the flavour of Binding Pledge and I really want to build a character that leans into it so a deal maker sort of character. It is only a level 1 so I could potentially get access to it through magic initiate for example or through the classes that get access to it, of course Bard seems obvious but I am also thinking that I need something to offer in return for said deals (other than do X quest), any suggestions? Does anyone have any experience using the spell for a character?
