Joomla 1.0.15 --> CB + JACLPlus + Template Design

My Platfrom is Joomla 1.0.15 I Require the following mods :- 1. In Community Builder (CB) Registration Page I need the users to choose their USER GROUP and SUB GROUP. i.e. From a drop down list, in the 1sr Drop down list they choose "Main Group" and in the 2nd Drop down list they choose the "Sub Group" E.g: - New York <--Main Group --- Chinese <-- Sub Group --- European --- Indian If the user is an "Indian in NY", he selects New York from the 1st Drop down list and Indian in the 2nd Drop Down list. 2. Use JACLPlus for custom user groups and assigning 2 or more GROUPS to a SINGLE USER, in form of Groups and Subgroups. E.g: - New York <--Main Group --- Chinese <-- SubGroups --- Europens --- Indians Assign a user the main group New York and his subgroup Indian/Chinese/European which he selects from the main REGISTRATION PAGE OF CB. 3. A custom template for "Joomla 1.0.15" very much like the front page of [login to view URL] , i.e Registration for of CB on the front page and a simple design. My main aim of the website is to register users on the website and send them bulk SMS by Mambotastic SMS RC3 according to their Region. If some more detail is required please PM me.
