256950 Cart and Skype incorporation

Hi, I created a website based on genealogy using The Next Generation software purchased from [login to view URL] It is php/ajax based using mysqldatabase. What I need incorporated in it is as follows: 1) Extra admin page to manage/create subscription plans to apply to users which need to be linked to our payment gateway.(this will use parameters based on disk space used/number of generations maximum, photo feature option) 2) A usage indicator to be displayed on all pages of how much of their accoutn ahs been used. 3) integration of skype 'online' indicator of members that are online with 1 click to skype call them (members will need to enter their userid when joining or updating their profile) 4) currently have text pdf of family tree option and want it to display the actual family tree as on the display. 5) the site uses stulesheets and want the menu to include next to it a 'enlarge/reduce' link for those that have poor eyesight. 6) Invite people to checkout the website feature 7) Tree admin feature is currently there but any new members currently still have to be administrated by the super admi. I want this to change so the tree admin handles any new memebers that are part of their tree. The base wbesite strucutre is very good and I have tried hooking upto both joomla and drupal (plus other cms systems) but they have their limitations. Some of the features above are relativ;ey straight forward and some like the admin, skype and sub account admin are beyond me. Those that succeed and complete the work to a high standard will have ongoing work from me. I look forward to your replies plus any questions. Of course I have no problem giving you login access to the backend plus ftp access to access things. The test website is currently at [login to view URL] You will not be able to see much unless you signup. I must see some work that is relavent to what you need to do on my website to ensure you have shown the ability of performing the task.
