"Because sometimes you need help."
Why pay someone to take care of your Google Sites website? Simply put, everyone needs help once-in-a-while. If you are a business owner or run an organization, you know the demands of maintaining a website while managing your affairs. There just is not enough time to master both.
Time
Nothing else need be said.
Expertise
You know enough to know when you need help. I can do those maintenance jobs you can't or won't do.
Convenience
You are not in the website business. So why would you have all the tools? I do. I work with Google Sites everyday.
Peace of Mind
Relax knowing that your website is being taken care of.
