Modify my existing 3rd party theme and Integrate

I would like you to modify my theme [login to view URL] so the customer creates the classified ad then they can preview the ad then pay according to how many lines without having to register. I want to collect the data "the ads" and be able to export to a format doc that I can transfer to my designer by email on a daily basis for my print newspaper. Is the checklist below doable? Basically see modifications below I understand some of these functions already exist. Checkout/Ad Builder Ad Content (character limiter/line) Ad Options (underlined, bold, etc.) (ability to add options and price in Drupal) Ad Duration Banner Image Upload Price Generation (real time or on click) Placement Levels (premium, etc.) [login to view URL] Integration Email Confirmation Order confirmation Approval Confirmation Email Notice to WHOA stakeholders Data Export Manual DB export
