vbulletin plugin

This is a vbulletin plugin project, basically you need to be really familiar with vbulletin software for this one.. alright, what I need done is a system which, when applied hide tags on a (vbulletin) forum, around certain text, that part of a post would be hidden, to selected usergroups, the person who posted it would be able to see that content, and other set usergroups such as administrators and moderators, but for regular members they would have to click the thanks botton which would be acknowledging the post, and once they've done that, the content is revealed to them... the system would also count up the number of thanks given and number received... (keep in mind that thanks can be given to any post, with hidden content or not, but if there is hidden content, only way to reveal it would be thanking the post).. other featues I'd like to have is vbulletin usergroup promotion based on number of thanks, leaderboard, and such... this method would be loosely based on out of date and unsupported vbulletin plugins which are available, but no longer functional as intended. if you need more info on the project please contact me.. Thank you
