Able to fix scripts that show errors

Look for someone skilled at coding any script by either fixing the error i have now or changing whatever script it is using for example if it is running flash being able to change to javascript or modifying the script so it can work. The script is an ecommerce script where people can customize any product users can upload images or write anything they want. At the moment the script i have works except for the fonts desnt seem to want to display them. I need someone who can fix this bug or modify it so it can work in my hosting provider.
