Let me point out a fact that most have not touched upon.
Since you / your client is willing to do this through cash, it would mean someone with that amount of BTC would have to meet you physically. Risking their anonymity and possibly endangering themselves.
Anyone with stacks of cash can get a gun and then point it at the BTC seller - forcing them to give up their BTC - since they showed up that must mean they have the BTC.
If this never occurred to you, then think about this. Possibly this guy (if it is not you) - is playing you along to find the right bait.
I am sure you are acting as an agent here, but I would advise you to let it go. Advice your "client" to buy the crypto online.
PS: Come to think of it, weren't you looking for investments into your project?
Anyways, good luck.
Yes that's occurred to me and the buyer. The physical meeting would not happen in a hotel room, parking garage, etc... It would need to occur inside a bank or some other secure location where both parties feel safe and comfortable.
As to raising money for my project, yes I am. This investor is interested in investing part of the money they have in cash in our project contingent on finding a BTC seller that will accept cash. The problem is they need someone that can get the physical cash directly into BTC without triggering a taxable event by depositing it into a bank account.
