@Raine whoa. you said you MADE UP an email and phone number???
What if they call the number? What cell phone will it ring?
I can fake a check stub for you and even an employee id, but you'll have to print it and get it laminated (kinkos can laminate with THICK laminate so it'll look good)
If I were you though, I'd go buy a burner phone (or register a google voice number that forwards to your number, and you can set it so whenever a forwarded call goes to your number, it'll show the google voice number on your phone, so you'll know to answer the phone with "Raine's Fake Business, how can I help you?") and make sure that's on everything.
Just let me know if I can help.
Setting up a website would cost you some money if you wanted to make it a legit domain name, e.g. Rainesfakebusiness.com and email would be raine@rainesfakebusiness.com and you'd have to have the hosting done somewhere, that will cost something too...
just depends how in depth they/you want to take it.
