Yes you can!
Can I do my own website?
This is NOT rocket-science. Anybody CAN make a single web page using Microsoft Word (click FILE>SAVE AS>WEB PAGE). For that matter, anybody can build a simple multi-page website using the tools and templates provided by many website hosting companies.
But should you?
It really depends upon that you wish your website to achieve and the image you wish to project.
Then too, your time is worth something -- probably more than ours.
Building a website is something we do every day. We are experienced and have at our disposal the latest in computer hardware and software tools.
