Combine Dating Platform and Twitter based php scripts

I have purchased 2 scripts: 1 - [login to view URL] 2 - [login to view URL] I want the second one integrated into first one and also want the features below added/removed. 1 - Remove all paid user plans, site will be free. 2 - Add invite only mode for whole site and a control tab for this option in admin panel. (to create codes, send them by e-mal, etc.) 3 - Give users 5 invites per user and let them send through e-mail address. 4 - Change signup page according to the invite only mode. 5 - Edit the user registration information which will be shown on the users' profile pages. Site will be a dating + twitter hybrid (users will be able to follow, RT, fav and mention the posts also will see the posts of people they follow. All of these features are present in the second script.). Please code according to that. I can create mockups if you want more detail. Please do not bid if you are not able to do this kind of work and you have more than %85 completion rate. This is the third time I am rescheduling this project because of disputes. I can deliver you the php scripts but in the end you will prepare an install package that I can extract and easily set up to my site.
