i would look at http://www.distilled.net/blog/distilled/guide-to-google-docs-importxml/ which should get you pointed in the right direction...basically you will be building a mini scraper to pull in the data you want from the search results into your google doc.

you could probably build something with Google Docs that would help streamline the process. are you basically interested in pulling the number from something like this "About 348,000 results (0.06 seconds) " - extracting the 348,000 number to use in your data? if so, it would take some work but could be done in Google Docs....

btw, you would be able to get up to 50 results at a time with Google Docs since they put a cap on the number of importxml functions you can run in a spreadsheet. but it would be better than running 50 different manual searches

Aside from what Ryan pointed out, I made it to the checkout page and felt very overwhelmed with all the information being asked. For the novice web user, they may also be confused as to some steps appear side by side, while others take up both columns. Maybe do some split testing on this page. For example, maybe use Ajax to hide all the required data for each step, and it simply gets expanded when clicked on? Would make the user feel less overwhelmed and at the same time able to easily see how many steps are needed to complete the checkout process?

Also, do you have a rather high bounce rate for the checkout page (/cart/basket/)?
