Is it possible to get started in this business with limited or no budget?

Yes, absolutely.

I am a web site developer and have a server that hosts my sites, so I have access to create and host as many pages as I want. But I do not have the budget to run a PPC campaign.

It's less popular in the AM sector, but you can operate entirely on SEO pureplay. If your site is considerably the best information resource for a given search query, any search engine looks uninformed if it doesn't display your site at the top of its list of results.
