Customize Authorize.net Checkout for Templatic Daily Deal Theme

I need to modify the checkout process for the Templatic Daily Deal theme. ([login to view URL]) The theme is using [login to view URL] server integration method and it needs to use Advanced integration so we can do a one page checkout. Right now the process to checkout using [login to view URL] is WAY too long. 1. Enter credit card info and hit submit. (Where I would need an SSL certificate for this page since you are entering credit card numbers.) 2. Then it opens up an order information page at [login to view URL] where you have to hit submit again. 3. Then for the order to go through and show the voucher. You have to click on " Click here to complete your transaction" in order for the order to finalize and the voucher to be emailed. Which I think a lot of people will not see this, since at the top of the screen it says "Thank you for your order!" I am looking to streamline this checkout process so that there arent so many steps. I have used other wordpress cart plugins such as cart66, where they offer [login to view URL] integration and all you do is enter credit card info on site, hit submit and the transaction goes through. In this case the user has to hit submit/continue 3 times to finalize an order, which is unnecessary. Please reply with timeline to complete project and price.
