Landing one website creation should be more than your $200 a month. If you're working with a CMS and are decent with it, I doubt it would take you more than a week or two.
It all depends on what you mean by "experienced with ...". If you truly are experienced with those things, editing the CMS should be easy, especially if you're working from someone else's template.
While the idea of gaining expertise and then going to consulting is one that is logical, it wouldn't make sense unless you really only wanted to consult and work in those industries anyway. Going in younger affords you to be not pigeonholed in a specific market (as you're cheaper) and lets you explore more different markets/roles.
