Looking for a helicopter school

As the title States I'm looking for a school that would give me a helicopter rating or someone that's a CFI/CFII instructor in or near El Paso. I'm currently in the process of buying a Rotorway Exec 90 but won't be able to fly it seeing how I don't hold a PPL. I've checked all local flight schools and called with no luck. If any of y'all know a school or somebody that's willing to certify me I would be ever so grateful!
