, okay, fly in to thailand, get the 30 day visa exempt entry, transfer the 400K baht into your thai bank account and then you and your wife IMMEDIATELY GO to the Jomtien Immigration office and get the hand out that lists the requirements so you can apply for an in country 90 day Non-O visa based on marriage for 2000baht.
The reason I say go immediately is that you need so many days on your entry stamp to do the in country conversion from a visa exempt to a 90 day Non-O visa because it goes under consideration before you go back and get the visa inked in. Don't dilly-dally around and you can pull this off without any problems at all.
