wordpress plug-in - need a demo version

Hi there, I have a wordpress plug-in I would like a demo version created. ** I don't need any other functions added.** I just need some restrictions added so people can't use all the fuctions. The plug-in has 4 main functions which I have listed below and the restrictions I would like on them. **Clone** This part of the plug-in allows people to clone blogs. I want the demo version to **not allow** cloning to .com domains or .[login to view URL] **Import articles** Limit amount of articles can import to 5. The full version has unlimited. **Amazon ads** Limit product posts to 5. **Clickbank** Limit so the ad size can't be changed from default values. That is it for someone that knows what they are doing this should be a simple job. cheers
