Danielle what you need is a trusted and verified hobbyist that it is agreed upon up front that you have never seen that it will happen at a random time and he will obviously where protection and give you your donation (unless your willing to waive donation if he does a good enough job) and of course the biggie is you will have to tell him where you live. So in summation. He must know where you live, and you must not know what he looks like. It will take a lot of trust but I'm are some of your provider friends have that you trust enough have a regular they wouldn't mind loaning out. Ginger Doll maybe... I don't think I would do it myself since I'm a pretty good "actor" and I'm afraid I'd get fucking shot or stabbed before I could say stop its me Ninja!! You seem kind of like a badass so I'd be scared.
I will take a freebie for having such a well thought out and great idea lol j/k
Also set rules upfront that you trust him to follow but keep them to a minimum and you might actually believe it's really happening
