I'm new hear too...First thing I did was registered my online business with the irs.gov website,got my tax id aka EIN...
Then just do random searches for dropshippers and wholesalers, find the suppliers you find interesting and save them to favorites... Open a salewoo store and slowly work on adding products to it. That's what I do everyday,try and find relevant products. Another thing I did was register a domain name for my store.. when you sign up for store,they suggest some cheap domain buying sites...I haven't got into promoting my store just yet,still adding products...but I will advertise on youtube once it's ready.. been posting on facebook and twitter now though... Also eBay is probably faster to sell stuff but website is better cause no fees,I also linked my ebay on website to offer auction deals to my customers on select items. I start the ebay items a bit lower to get customers,if they want to buy from website they can too. also adwords is good too,I'm using that too. But I'm on the manual funding,so I make a payment to adwords once funds run out,they stop running my ads till I make another payment. I wouldn't put it on automatic cause they might charge too much for ads...
