The fund is the key to getting the endorsement.

Therefore we need to ensure that the fund is as legitimate as possible.

Lawyers may be too expensive, but as others have mentioned, getting a public figure connected to Trump whose reputation is more important than money to hold the account in escrow is the key.  I highly recommend trying to contact the likes of Milo Yiannopoulos to do it.  He's extremely wealthy already, deals with legal shit all the time, and his endorsement alone would cause the price to skyrocket.  He's also moderating both of the large donald trump subreddits, and likes 4chan /pol/, so he's in-tune with internet stuff like this.

Full disclosure: I hold about 15k Trumps and want to see the project succeed for my own personal profit - so I'm not a hillary shill or whatever, lol.
