I want my company information to be defaulted as the Invoice to, Sell to, and Ship to.

Add your company as a Client Company. 

Using the screen below, make sure you add the Company Name identically to your company name.  Then, every time a new project is created, your information will be the default into the sell to, invoice to, and ship to information.  Make sure you don’t click the ‘Don’t Save this Company’ check box (on this screen, other screens will not have that option.)
