Website maintenance is something that can be done by you. It is fairly easy and requires really only basic word processing style skills. If you can write a letter in Word then you can update your pages.
That being said, many business owners do not want to maintain their own websites. This can be for a variety of reason and any one of them is okay.
Whatever the reason, I can maintain it for you. Just let me know what you want. I will make recommendations and we will come to some sort of agreement that works well.
