That's the goal of PPC - Pay-Per-Click, also called "SEM" Search Engine Marketing.
SEO can be tricky, difficult, and unreliable, but you don't need to choose one or the other - choose both! Most SEO experts start with PPC just because it's faster, and like renting a house, you "move in" immediately. This allows you to verify which phrases are going to convert the best.
One-time investment to setup your Google Adwords account for advertising and get thousands of unique visitors. We'll also advise you of expected cost-per-clicks so you can start to get a sense of your cost-per-new-client.
This also includes keyword research, which you'll need for SEO and content marketing anyway, and is the #1 best place to start if you've never made any real money online.
Note you need a website or landing page - an offer - for this to be any good. We'll setup the account, then can either turn the keys over for you to manage in ~ 1 hour a week, or you can subscribe to on-going management services from us or others (packages available from $100/mo).
