Everything possible- but do look for alternative, and have to be more confident in yourself. Don’t limit yourself with the amount of money or business limitation rather think that there is plenty of other opportunities clicking while you are here as in initially might be a struggle! I would suggest to start some job that gives daily life expenses and experience with local network which eventually will help grow your business, by the time you get self acquainted more with place and people it will be more smooth to prioritise. You can definitely arrange a fix source of income as job and other club business to make sure sustainable life in Thailand. Me and wife started with 10k bhat products on e-commerce platform with 2 years having 200k stocks with 500 loyal customers. Life might be struggle or challenge but it’s adventure and the joy of doing something small and growing is amazing . You can look for many jobs in hospitality or education for field etc, don’t limit yourself on 1 business idea with limited amount but try to make multiple source of incomes. Good luck
