at most offices you can come in free stamp 60 day entry, bank the 800K baht and apply for the 90 day Non-O visa in country for 2000baht. it goes under review for usually 2 weeks then you go back to get the Non-O visa and a new 90 day stamp inked in. Then 2 months later you apply for the yearly extension

it's not a hybrid anything, many MANY people do the in country Non-O. Although with the difficulty in opening a bank account free stamp it is often easier to get the Non-O in your country before you come here, so you can open the account and get the funds in
