CSS, Javascript and Buddypress work on adult website

Hi, We're soon launching an XXX adult website, but there is still work to do. 1- The comment system shown nested comments but we only want 1-level comments to show up (CSS). 2- The rating system (custom made) does not "save" new ratings, so we must fix this issue (Javascript). 3- We'd like to add the bbpress forum plugin into BuddyPress. 4- We want to link the ratings and comments to the BuddyPress activity. For example, when someone rates and/or comments a movie, it must show up in the BuddyPress activity. The rating system is built-in (very simple) and the comments system is Wordpress's comment system. If you want to give a look at the website, just ask for it. If it's too complicated for you to give a price, I can buy a bank of hours and we'll work from there. Tell me what's your hourly rate or your price for 20 and 30 hours. Thanks !
