Although it's clever, your brand name is kinda clunky to say. Even enunciating it requires some practice, which customers will find awkward and possibly offputting.
While you're still figuring out how to get your name out there, now is a good time to make sure you've got the right name.
I know you can do better, although you may not like my saying so.
As far as PPC advertising goes, here are a few ideas:
(1) Facebook can help you zero in on the right age group.
(2) Google AdWords can put you in front of people searching for ghost writers and self-publishing services. If they're looking for similar topics and nearly ready to check out, then you want them to see you alongside those other options.
(3) You may be able to think of other search verticals of particular interest to baby boomers & seniors. Perhaps as a group they're curious about genealogy, looking up social security or IRAs, or even (dare I say it) age-related health problems.
Additionally you might want to make a list of bloggers who cater to that demographic. Some well placed advertorials can get you noticed.
