Local Search Toolkit
LocalSearchToolkit.com is going to offer a comprehensive web based tool set to help agencies and business owners with local search or local seo projects. Eventually we'll also offer services revolving around local search as well. You can find a complete and total placeholder site at http://www.localsearchtoolkit.com which has some information on the tools.

Icons representing tools like a gear or widget
Really we'll leave most of this up to you creative geniuses.
