We offer a hosted store locator service that allows companies to embed store locators into their web site. The store locator has a full API that has been used to develop many custom interfaces as well as a Facebook store locator.
We would like to develop a plug for Word Press which will allow Word Press users to integrate the same functionality into their Word Press sites.
For project details please see the specification document attached.
If you are interested, I can provide a link to the API documentation.
