Contracting firm involved, at least at first. Don’t try to set it up yourself or you’re guaranteed to mess something up.
But to answer your question, I’d plan on somewhere around $50-60k all-in and depending on how much experience you’re looking for. Could be significantly lower for someone with little to no experience or a little bit higher for someone with a lot of experience. If you do a contract agency obviously it’ll be on the higher end as well
