Starting an online business basics?

Hello I feel completely lost when it comes to this. Could you layout what exactly is needed to start an online business in Texas? I would like to sell stickers and other crafts on Etsy but not sure where to start? I've looked up things on the internet but there's so much information its overwhelming. So I have questions such as:

What do I do first?

Would I be considered a Sole proprietor or an Independent Contractor?

What licenses to I need?

What forms do I need or does the website send me the correct tax forms?

How specific does a name have to be to not need a DBA?

Do I need to get a CPA?

What type of advisors do I need or do I need any?

If not you guys who do I talk to about starting this up a lawyer, a CPA or another type of advisor. 

 

I really need a lot of guidance and am starting at the very ground level of this journey and interested in giving this a try and want to do it right.

 

Thank you for your time!
