Start renting a location that's close in Singapore, or USA Nevada, or Vietnam, or Hong Kong
Why these locations can ship for free and under cut sellers, as they offer almost free postage, then you need to negotiate your product.
Will you be in your country doing all the over sightseeing, or hiring someone.
Have you researched the product, do you have. Platform in mind apart from eBay?
How much starting money do you have:
$50,
500,
5000,
50,000.
How long are you willing to commit for?
For:
2 days,
2 months,
2 years,
Or do or die.
These questions are important as you rise in the food chain.
Once you have a idea then you can sell and make money.
This is for whole sale at a large scale, it can be reduced.
You can flip stuff in your local area on your community sub forum.
Be mindful the higher the cost in item more money ebay makes, and if its heavy it will eat through your sales.
Dropshipping is brutal.
