Hello Dan
A good G1 is an option and as you know the acquisition price is low , that means a lot of capital left for the fairly high operating cost, if you only plan to fly 100-150 hours a year it's certainly will leave a suitable amount of downtime for the maintenance. Make sure you get a well experienced Engineer he will save you a lot of head aches. Also a high time turbo prop pilot who's looking for a semi retirement job would fit the bill, do you plan on having the aircrew on a rotation basis as well ? BTW it will attract more qualified crews.
Make sure you get in touch with Gulfstream in Savanah GA they should be able to provide you with plenty of good leads for Maintenance crews as well as pilots.
Good luck with your project, and my hats off to you for trying to establish a first class operation for your employee's
