I would recommend if this is the route you are going to go, do all the legwork first before you spend the cash. Post to the API forums about what you are planning to do and need for the script, get characters built and ready for the import, and get the rest of your game ready for use then drop the money, install the script, and import your sheets. I suggest this as there are things that could go wrong and you could be out the ten if you don't get it done in time.
