depends on what kind of consulting you'll provide. if it were to be
professional service that is professionally regulated eg.architect, doc,
lawyer then u would need relevant professional licenses to practice.
Otherwise there are no particular requirements to form a consulting company.
It's generally very easy to form a business entity. For most states, you
can easily register a company online. The tricky part is which entity type (
i.e.sole proprietor ship or partnership or llc or S corp, c corp etc.) would
be best for your business needs and also optimal from a legal risk or tax
perspective.
