I’m looking for a lawyer to help with registration of the company

In setting up an entity, there are many issues to consider such as taxes (TN and Federal), filing fees among the various types (LLC, S Corp, C Corp [less likely to be used]), type of ownership structure (even among entities, there are different types (e.g. 3 types of TN LLC's), insurance costs.  Our firm can help with all of these issues as part of entity formation.

You need to first decide what type of organizational entity you want to establish. Then you register with the Tenn Department  of State and Department of Revenue and you need a tax FEIN number for the entity. You be best served going through this with a Lawyer in person
