Yes many low level and amateur even starter fights so with shinpads etc both boxing and Muay Thai ...in Phuket I’ve seen new people Fight but they start with no protection at all depends on what you prefer l.
gyms are expensive anywhere in Bangkok you can find some for 4000-6000 ,Muay Thai academy is only 2000 a month even
Chiangmai/ Phuket and most other places are 10000 a month for most gyms .
If you can get down to 78kg even only for the weight in that’s mostly a day prior you will be fine to get fights and to be honest it doesn’t come that close a few kg give or take is fine I’ve seen it a lot here .
ive had a lot of opportunities myself and I’m fighting around 78kg , it’s mostly about finding a trainer who cares and he will help you out I’m based in Bangkok myself but my trainer offered my fights everywhere , I think most of them are connected with promotors anyway from their past .
But if you are alone I would definitely choose Bangkok more contact with other foreigners / more Thai that speak English and easy public transport (cheaper grab and taxis too in other city’s they can be way more expensive ,Chiangmai and Bangkok are the cheapest , Phuket and Pattaya really expensive)
send me a pm if you want some specific info
