I thought about hiring somebody five years ago, but the fact is my client has gone itself from a small/medium sized business to a corporate, from no IT staff to now thirty and they are working to replace the production systems I wrote the middle of this year. To be frank having that much responsibility as a one man business is quite scary. Also when I originally wrote the systems for them I had no clue it was going to get this busy and no clue I would be 24x7 support, also at 62 years old I really want to start winding down :-)
