-my 10 year old son can build a website for my business; should I let him ?

Depending on what type of business and your goals for the website, your son may be able to do wonders and save you some money at the same time.

For most businesses however, a professionally developed site is likely the better choice. In any business environment, first impressions are critical. If you are a plumber or a mechanic, you may not need a professional site.

Otherwise, you may want to consider simply letting your son coordinate the project with the help of a professional design house.
