Data Mining Software like Mozenda (feature wise)

I am looking to have a data mining software created which can crawl websites capturing text or images, to best describe the functionality would be to say a software package just like Mozenda but it would need to be a stand-a-lone version, meaning not web based. It can also not be an existing software package re-skinned either, like some o fthe open source versions available on the web. It must be a new design specifically. Please PM questions or concerns regarding the project or if you need additional information. Ideally, if you review the Mozenda software you will get what we require, just not web based as Mozenda is.
