Parental Internet Filter / Parental Control Filter In Delphi

I'm looking for someone to write a parental internet filter solution specifically in Delphi. The code would be incorporated into pre-existing computer monitoring software by myself once finished. I need the program to: Filter websites based on keywords Block all websites and only let certain sites through I'd need to be able to add to the list of keywords easily and have them orginised into categories I presume the software would receive the page (through a proxy maybe?) scan it for the keywords and if none are found display it. If keywords are found block it. Any other parental control features that could be added would be a big bonus (ie only allowing internet access at certain times or limiting the amount of time per day that the internet could be used) As this will be incorporated into an existing project, pretty design/ui is not needed. If you have any questions please let me know.
