staker2, you've received some interesting advice. I think Duncan Pollock's observation about your skillset is especially insightful. I also don't think he takes it far enough.
craigmn3 also points up how competitive the
SEO field is.
So, if you take both those opinions into account, there is a third option. Might I suggest that if your strength is in your writing, that you consider doing web copywriting? Though it is also competitive, from what I've seen there are only a handful of people who are truly good at it. The rest I've seen are truly awful. I recently had need of this service, and routinely saw grammatical errors, spelling mistakes, phrasing issues, and an overall feeling of "snake oil salesperson" in the copy that the so called web copywriters used to promote themselves on their own websites, and in the samples of their work they provided. So my feeling is that there is a need. And if you have good writing skills, and an overall knowledge of
SEO, this should be within your ability, though it may need a bit of work to develop those particular writing muscles.
I also don't think that the web copywriting field is as prone to rapid change as the
SEO field, though there will always be changes in any field. So I think it's a more stable way to make a living. Just my two cents.
