Business Idea expanded...would like more idead a suggestions.

As far as starting a computer clean up business by making house calls with the computer handicapped.

I am thinking of a $100 fix it fee for most problems.
This is $40 less than the geek squad.

Also I was thinking of a $70.00 computer check up/tune up.
Check for Windows Updates and schedule for automatic updates.
Check for virus and firewall software and check to see if it up to date.
Scan for any viruses or spyware. (longer process)
Run Hijack This....great program.
Install Microsoft Anti-Spyware and Ad Aware with client consent.
Delete all unwanted program (weather bug and mywebsearch typical)
Defrag and install and run ccleaner.
Speed up the start up and shut down process.
Provide client with information about basic virus/spyware prevention and computer clean up and Maintenance.

Any other ideas???
Anything would be great.
