The biggest mistake I see people make when they optimize for keywords is going for more than one keyword phrase per page. You might try to make your homepage rank for
Pittsburgh Photo Retouching
and your about me page
Pittsburgh Photo Retoucher
and then, ideally, you'll write a blog post every Wednesday and pick a new two- or three-word phrase that's related to your field, and write good, original content that is conscious of that page's targeted keyword phrase.
As long as the pages have original content, you'll likely be able to start ranking for some keywords. I disagree about Google ads. The most important thing is to play along with the rest of Google world. Get a plus page, activate authorship, write a blog, and blog about what you do as you're doing it. If you have a physical location, get a places page. Get real, positive reviews. Make friends on plus in the photography world.
Google can't easily look at what happens on private Facebook pages, but it can track what is shared on Google Plus. The search algorithm needs to extrapolate what's happening on private social networks by weighting Google Plus activity more heavily.
If you're having trouble planting the first seeds, it can help to do some guest blogging. You can also get your first inbound links with real-world networking, e.g. offering a free workshop "intro to retouching" might get you some links to your blog post about the event. Those relevant, timely, organic links make a huge difference in SERPs.
