Need To Add 'Invite Friends' Functionality To Facebook Appli

I have just launched a dating application on Facebook. To add the app, new users go to the Application page and press 'go to app' - this launches the 'request for permission' / OAuth Dialog window, where by my site retrieves certain fields from their personal data. After they press 'allow' users are then taken to my app where they begin to build their profile and use its full functionality. What I would like to hire someone to do for me, is change the process slightly so after they press 'allow' to share their data, instead of being taken straight to my app, I would like the users to be given the option to 'invite friends' to use my app. This would mean that my App would then appear in the 'app requests' page of the users who were invited, thus providing me with more potential users to my application. I beleive this is a fairly standard proceedure to complete. Also - on the homepage of my app once launched, there is a button which is titled 'invite friends'. At the moment it is used to invite friends by users filling in a standard form with their friends email addresses which my app sends out manually. I would like to replace that functionality with a link to the same 'invite friends' box on Facebook, so that even after users have launched and added my application, they will still have the opportunity to invite friends each time they log on if they so wish. I have attached a Word document with an example of the type of box I'm talking about - hopefully this will make it clear but please do contact me if you would like more detailed information or clarifiations regarding my Facebook application and the job I'm hiring for.
