what type of FFL are you?
as per federal law, interstate transfers require that handguns be sent only to FFLs in the State of the recipient. As long as you are an 01 or an 07 FFL in Indiana, there should not be be any restriction for him to send the gun to you as an FFL via FedEx or UPS (in other words, not USPS). You enter the gun into your book twice. Once coming in and the second time out to you.
If you are an FFL, how do you not know this?
