Sounds like a small business so consider a bunch of things. You may want to use a "headhunter" company to find someone who meets your requirements. It would also be nice to find someone who is close by and since your going to spend a lot of time with this person, its going to have to be someone compatible.
Plenty of Helicopter Drivers out there, but may not be many that also meet the needs of your company? Occupation?etc.
Take your time, it will happen..........besides its not posted what business your in.......hate to recommend a Pilot with experience in Ladys Lingerie.........
