Thanks again for the comments!
I think Peter is right about the "free" servers not being able to do the job. I will have to look around and see what else is available (and hopefully, cheap!)
On McGrath's website, he recommends RealAudio (or RealPlayer) which is streaming. But the "sample" idea is probably better.
I do plan to put out all the songs on a disc for sale, eventually. And yes, I wrote all the songs and perfom them on the recording with other musicians I regularly play with, so copyright is not an issue.
This is new territory for me, so thanks for the help :)
