Lead Generation and Email PDF Integration

My company shows at a lot of tradeshows and would like to go greener by not handing out flyers to our clients and potential clients. We are looking for some kind of plugin that might have the functionality where we could upload our marketing flyers and our customers could go to our website, choose which flyers to email themselves, fill out a form (so we have lead/contact info) and easily email themselves the flyers that interest them. Right now, we are using multiple tools (non WP Based) and are trying to streamline this process as we build our new website. Please let me know if you know of any plugins that can help!
