Creating different page for every city and county is someway spammy and actually doesn't give great user experience... just think if you would like to visit a site where are "tons" of pages, actually not adding anything valuable to the website.

Create one page where you can list in nice list style cities you offer your service and look for interesting local directories where you can add your business. If any specific city is more important than others... you can create an article about it... like... How to Find Good Pool Cleaning Company in New Jersey... and give some good tips how find company, without excessively promoting your own company... you can refer there to review sites and other places, where your business is listed and has good reviews...

About local listing, you can find some information here: http://www.seomoz.org/blog/the-beginners-checklist-for-small-business-seo - but for this one is important where your business has office.

Hopefully it's useful information Bill, good luck with business!
