Typcially, these types of companies have the homeowner pull the permits and then have an experienced, but UNLICENSED "project manager" manage the project. I know of a couple of guys who do this and the reason that they are unlicensed is because they had their license revoked for various reasons. It is legal, but I would be very careful about who you are hiring.
Also, there is a state law that forbids rental or sale within two years, of any property that was built by a non-contractor owner. If you pull the permit, you are the builder.
