Module development required

I need specific functionality for the Opencart shop.
Here is an example of what is required:
http://www.frames4sale.com/LensPrescription.aspx

Please fill up the form and follow it (there will be a few pages of the same order process). So, I need a button (i.e. Rx Lenses) always available for a user); when user clicks on the button it gets into ordering process similar to the example above.

It can be a module or other solution - whatever to get it done properly. Please contact me if you are interested.
Best regards.

We gone through your requirement.

We are interested to work in this. Can you please let me know further about this.
Thanks in advance.
