State tax filing

Thanks for the advice. 
Here are some additional conditions:
There are more than 40 states in which our current orders have been placed. So we will need to register and sale tax returns more than 40 states. This will be a massive job for a starting business. 

Could you advise us a better solution which is more suitable for our small business? (for example, could my first assumption which is pay the individuals back work legally? )

 

Sincerely appreciate your kind.
