Webcrawler for Wordpress

Looking for a developer who can develop a web crawler that will integrate with the latest version of wordpress as a plugin. This web crawler can use a specific set of keywords and expressions to crawl websites constantly and find information based on those expressions supplied so that the information will be posted back to the wordpress site. For example if you add the following keywords DEVELOPMENT and DOT and NET, this will make the crawler add to the wordpress site articles written about development and dot and net. Articles related to the content will be linked to the wordpress site including the url of the source for referring back to the original site. The crawler should be able to allow multiple expressions added and should exist on its own when crawling. It should be able to indefinitely crawl the web until deactivated in the wordpress admin plugin section. We will receive exclusive rights to this plugin so that it will not be used or distributed by others. There will be a NDA (Non Disclosure Agreement) we will provide online which you will need to agree with upon beginning this project. When posting your Bid please advise what languages will be used (php, js, as) and how you will develop this. Please do not bid that you are ready to work, your bid WILL NOT be considered. We want developers who can think and advise when working on this and maintain good communication on a daily basis. If you do a good job, we will have more projects for you.
