Although all of the suggestions above are valuable, I think it depends a lot on the products and services you intend to offer. If you're doing landscaping for people in your small town, for example, maybe the website isn't an urgent thing right away.
The key thing--and I guess I'm throwing the question back at the original poster--is to figure out who your customers are, what they want and will pay money for, and then what it takes to deliver that and sustain your operations at the same time.
For some, a cell phone and simple WordPress website will do. For others there could be substantial office equipment and a custom software development project. It's so hard to know without more background information.
