I think you might need to explain a little bit more about your problem. For example are you using a custom script or specific shopping cart software? Is the problem with the script being used to send spam or some other problem?

Is the website still up? Did LP disable the script that was causing problems? You say the "order now" page was beat up, what exactly did the page do originally? Was it just a form for customers to enter contact details that are sent via email, or was it more along the lines of a shopping cart where orders were accepted and credit card payments were processed?

Perhaps if you can quote the email LP sent you-minus any confidential account information, we can decipher the "chinese" for you.

Once you're clear on what needs to be done to get the problem fixed services such as www.RentaCoder.com and www.Elance.com can be used to locate suitable people to do the work for you.
