Working within a budget sometimes can have its restrictions. But the easiest thing you can do on a tight budget is get your web site on the web. Even a single page describing what you do will at least get you listed in the search engines. You can always expand later as you see fit.

The most frustrating thing for new web site owners is not showing up in search results, as it takes time to get indexed so people can find you when they are searching for your products.
