Landing Page Optimization - AdWords Question

I know that having a landing page with relevant keywords will help my QS and overall AdWords success. That being said, I was wondering how people implement different landing pages for different keywords - especially for a small business site.

As for my example, I'm a hypothetical chemistry tutor in the Boston area.
I have a simple website with these pages: home, about, services, contact. The services page is the landing page I would like to use to target my keywords It says, "Hi, I'm a chemistry tutor it the Boston area and I am available for services in the Boston Metro area."

With my services, I'd like to target towns around Boston. So I have the following adwords keywords "chem tutor boston ma, chem tutor somerville ma, chem tutor medford ma, chem tutor brighton ma"

If I start listing (forcing) all of the keywords on my services page it looks ridiculous. I can't say "I'm available as a chem tutor in boston ma, a chem tutor in somerville ma, and as a chem tutor in brighton ma", etc.

My goal is to have a true to form services page that has my real (and not keyword overstuffed) services explained, but attract to as many people in the surrounding towns as possible. And while there may be 10 towns I'd like to target, and I can't put them all in keywords on the services page.

So what should I do? Do I really create a custom services page for each adwords keyword, so that the pages is the same, but the line is "I'm a chem tutor available in [insert town keyword here]?....And then have a services.html page for direct link users, but have other pages for adwords users (services-boston.html, services-medford.html, services-brighton.html).

It seems a little strange.....

Thanks.
