I have a business where we sell entertainment services for mostly $20-100 each product. Our average revenue is around $150k/ month. Is there a chance our bank (Wells Fargo, or another) could hold our funds? Is Coinbase the best merchant to go with?
I think most people use BitPay, bitcoins you receive will be instantly converted to fiat currency, and deposited to your bank account. I haven't personally heard of this causing problems.
Coinbase would be good if you want to hold your coins, but beware of price fluctuations.
On a semi-related note, maybe consider using a credit union instead. Screw commercial banks ;-)
