Very nice project. However, the cost of the report is completely hidden, and I think a lot of people might get angry and close the window out of spite.

Also, what does the full report give me that isn't in the little thumbnail thing? Also, how can I tweak anything? It looks like I have to submit the whole thing over again with new data.

Maybe you should save the data in your database, generate a hash, and on submission take the customer to a page #1: They can link someone else, #2: with all the information from the little thumbnail thing, #3: with a clear explanation of the full report and the cost. This way they can also tweak and save the data when they get new information. They can also link the free page to other people who might buy the report.

Finally, there doesn't seem to be much unique information in your about page. Maybe you should move your about paragraph and contact form into the footer and get rid of your navigation altogether.
