Quickest way to get a bank account is through an agent though you pay for their services. I used Western Union and Wise to transfer from the US and found Wise has the best exchange rate and transfers are almost instantaneous.. Not sure of transfer limits though.
As others have commented, simple procedure. Be prepared to wait at immigration. If going to Pattaya or Bangkok you can pre-book a ride thru Nan's Lady Taxi service 1200 Baht. Always reliable and online.
