Your budget will determine which markets to explore. You may choose the USA if you have between $18,000 and $25,000 to spend. The UK is an option if your budget is between $12,000 and $15,000 USD. KSA, UAE, Australia, and other small markets are options if you have a budget of $5,000.
Location is the second consideration. It is advised that you use a marketplace where you may open an account for selling with ease.
