But he already stated that he is facing some limits because of Coinbase. He is talking of some limits per day/per month, so I believe even his bank is involved. So even if you talk to Coinbase, it's a waste of time if the bank won't allow it.
He is facing the usual limitations that all have when we join an exchanger. All the exchangers have those limits, but they can also all surpass them if you want more. However, you need to contact them, because AFAIK, they don't say anything in their FAQ for such cases (except one or two).
I don't know if OP has a limitation issue with his bank, but since he says that he wants to buy a 100k chunk at a time, I guess he has already talked with his bank and knows if and how much.
By the way, I think that OP is just another troll wannabe whale who wants to phish something out of this "issue"...
