How can I obtain a Non-B visa in Thailand using my diploma?

Masters degree in Teaching English to Speakers of Other Languages. Should have been a breeze but was a real nightmare with having to take them to the U.S. Embassy to get them certified but they only would have me sign an affidavit attesting that I had graduated on dates indicated. Fortunately the Ministry of Foreign Affairs accepted that and have me the necessary stamp.

We've got a difference in Englishes here. In the U.S. a diploma is a piece of paper you get finish a school -- high school, college/university, masters, doctorate, etc.

That said, the qualifications required for a job are really different from place to place in Thailand. In Bangkok you have to be Good -- very Good -- lucky or connected. Many foreigners want to be in our around Bangkok so competition is fierce. A project manager-engineer friend is teaching English in a small place in northern Thailand and he's by far the best one there. He says half the other "teachers" are not teachers and some can't speak English. They just have a foreign face.

I suggest that you look for work as a cyber security spook in outlying cities, learn to enjoy Thai provincial life for a few years, get a name as being Good, reliable and honest, then move into a job in a tougher market. I'd say it would take 3 to 5 years to build a good reputation unless you're absolutely brilliant.
