Introduction: What distinguishes my business is: (1) I am primarily computer and network maintenance. (2) I seek to keep you running at more-than-reasonable rates. (3) I am not a salesman, and I will not be setting you up to employ me further.
Do you have no one tech savvy on-site, or someone who doesn't have the time and can direct me to what you want done? Say you are a doctor, veterinarian, yoga instructor, et.al. and know next to nothing about computers. Let me do your computer/network maintenance and be gone, yet always available.
I can provide conservative recommendations for successfully moving forward (or grandiose, if you prefer).
