Not bad for one of your first hubs. I recommend putting quote-marks around your two headlines; otherwise, these statements seem to be yours.
The final section about buyers educating themselves (optionally, with your help) is too vague to be of any use. Consider providing some places they can go for information, and make it clearer how they might be able to ask you questions and get answers from you (e.g. comments, by contacting you through HubPages, by visiting your personal website).
