Welcome to the forum!
For starters, I suggest starting off by practice selling stuff from around your home. This will give you an idea and eventually feel comfortable with the online selling routine. Sell them on eBay, Craiglist, or even at your local auction sites. This will also let you know which products sell well online. Also, feedback on eBay is relevant for buyers to know whom their dealing with. With a feedback rating below 10, it is going to be difficult to get people to take you seriously. The higher your feedback, the better!
After some practice, I recommend buying small wholesale lots that most people use on a daily basis. Some ideas below:
Clothing: plus size, maternity
Kitchen: recipes, knife sets
Beauty: sunscreen, insect repellent
Homewares: towels, sheets
Special occasion: wedding supplies, party supplies
Garden : lawn mowers, gardening tool sets
