how to get a wp for freelance teaching

[juno]

i am 24 years old, married to a thai, planning to be p.r. in thailand by getting 3 x 1 year marriage visa and than immigration visa. i dont have any skills in teaching and only got my h.s. diploma. i am planning to open up a small store, sell Buddha frames, and freelance teaching. the only problem is that when i went to obtain a work visa or a work permit, they told me they cant give one for freelance. i need to be working in a school. they told me i am not aloud to teach from home or at peoples homes. WHAT AM I DOING WRONG? HOW CAN I GET A WORK PERMIT FOR FREELANCE TEACHING? i am worried about surviving in thailand if i cant teach as extra income apart from selling cigarettes, beer, pop, coffee, and Buddha frames.

does anybody have any advice on what my options are? i am living just outside Bangkok and i did try to get a job at some schools (but you need a B.A. or some kind of training). should i just teach at home without a wp? (i kinda want to do everything liegal because my wife is 7 months pregnant and i dont really have extra money to pay any fines).

thanks guys.
