These are questions you should try to answer before you decide to develop an Internet presence.
I will be interested in helping you determine the answers to:

Who is your audience?
What do you want the visitor to do?
What do you want the visitor to know about you and your business?
How do you want to interact with visitor?
Would you like to post testimonials, sales brochures, internet billboard, photos etc. of your projects?
