Hello I am wanting to start an online business selling on eBay and Amazon. I have an LLC business currently with a partner but want to keep my new business separate. I only wish to do a sole prop with dba for my online business. Is this ok to do this way? Can I have a new EIN number for this new dba business? I'd like to keep from using my ss#. On ebay i will have two accounts for buying and selling with different screennames but both will be tied to the same paypal business account and the business paypal account will have the same name as my dba name. Is this ok? Confused. Thank you for any and all advice.
