Problem you will have unless you can find a friendly bank is opening a thai account on a tourist visa, the 800 k needs to be in the bank a FULL 2 months before your visa application and has to remain at this amount for 3 months after your application can then drop down to 400 k for remainder of the year until 2 months before you apply for extension of stay.. if you can get an accountant opened then another alternative is to transfer 65k each month for 12 months (can't miss a month and double the payment following month). This monthly money has to come from outside thailand
