I really don't want to criticize the OP, but as an observation, the question reveals such a deep level of naivety about how to run a company that it bodes very poorly for the transition of this company to same-but-multiple-time-bigger-and-more-profitable.
Step One: talk to a local temp-to-perm agency about computer literate clerical staff or a personal assistant. This lets you defer ALL the HR/payroll/tax issues until much later.
