Visas are acquired outside of Thailand. You do *NOT* want a Non-O visa, or a Non-B visa. What you want is an extension of stay based on marriage, or an extension of stay based on employment. Both of these extensions are renewable and let you stay in Thailand for one year.
An extension of stay based on visiting Thai family is good for 60 days, and will put a "hard stamp" in your passport. It should be post-dated September 27, letting you stay until middle of November.
To get an extension of stay based on marriage to a Thai national, you need to make 40K THB a month. To get an extension of stay based on employment, you need to make 50K THB a month.
