okay, lets sort this out (and I deleted Jim Malkin comments because it appears he has me blocked and the information was NOT correct)
@Chris ******
you can't use monthly income for getting the initial 90 day non-O visa or the first year extension inside the country. That's because TO use monthly income you have to transfer IN from abroad to a thai bank account in your name only a minimum of 65K baht a month each month, every month for the previous 12 months before you can use that method.
This means to do it INSIDE the country you need to use banked money method the first year THEN you could switch over for the second year to monthly income by transfer each month until your next extension was due
