Its spring and I was thinking about cleaning computers

I had this idea that has been in my brain lately and finally decided to ask your opinions on it. Would any of you would have interest in some one to come to your house and clean up your computer? Say this person would come to your house twice a month and would run anti-spyware programs, update your system and generally clean up the operating system, and if necessary do minor repairs or upgrades. I was just wondering, your responses would be greatly appreciated.
