Do you have a MS license? A resident MS license would allow you to carry in all states you listed except NV (I assume NE=NV) and NM. If you have a MS resident license, FL would probably be the easiest non-resident permit to obtain that would pick up NV and NM for you. Looks like it would also pick up ND, OH and PA for you.
See handgunlaw.us to compare CC coverage. Be sure to note that several states only recognize resident permits.
