A bit tweaking needed on SocialEngine4 site

Hi, Due to my own busy schedule, I need somebody with excellent PHP/AJAX skills AND Social Engine customization experience. Please note that ability to install SE and add/remove themes/plugins does not constitute as customization skill or experience. There's not much to do, but if you are not familiar with SE it can take hours. So do not bid for this, if you do not have solid SE experience. So, what I need: 1) Minor main menu customization 2) "User pyramid" page. It should list users based on the way the users invite their friends and join the community. ie, if one user joins and invites 10 friends who each also invites 10 friends then the original user should see 100 users in his pyramid. Invite system is already in place, also the database logic. What is required is visual output. As some users' pyramids might get quite big, it should display the users on the page like google maps. ie, users are represented by small images and they are connected to each other, with the ability to zoom in or out (like Google Maps zoom toolbar) in order to see entire "pyramid" or to zoom in to see users with bigger pictures. NB! Users should not be displayed exactly in pyramid shape, more like just an overview of the people that have joined the community through particular user. When bidding, please write about your SE experience, some urls would be great as well. Also, when reading a bid I what to see from your bid that you have read through this text and you understand that you are bidding on. Payment will be made through milestone. NB! This is rather urgent project, so I expect the job to start maximum 3 days after confirmation.
