Pentaho report for embed

I need someone to customize a web launcher for pentaho reporting engine. I have the pentaho reporting engine and the designer and I have designed reports in it. What I need are two fold. I need someone to make a launcher that I can embed into my web page with a print now button, I should be able to pass parameters to this launcher file. This launcher file will accept parameters to pass to the report being printed out, like special filtering information for the report. Basically allow any number of params to be sent and the report just gets them. Also the launcher must accept one param itself, the report name param. This param will tell it which .prpt file to load from the server into the standard pentaho print preview window. The second part is once this is done I need this same person to show me how to grab those params sent to the launcher inside the report I design inside the designer program so I can pass it these filter params.
