Catalog for Ipad

Hi there. We are a growing company based in the UK but with offices around the world. We are looking to create a "catalogue/presentation tool" to run on an Ipad. This would show the product range, images, videos, white papers and so on. Ideally, we would like the ability to just have the app template and be able to add the information as required. This would then run on an Ipad for trade shows, presentations, and ideally to integrate any leads directly into Salesforce (our CRM) Ideally, someone who has an existing package compred to having a custom made one would be ideal.
