Fix some fucntionalities of a existing Social Networking script

Hello, I am looking for help to resolve some issues with my Sngine website. Here is the codecanyon link of the script: [login to view URL] Below I am listing the issues I need to fix, and please let me, should I directly order this service? 1. Options to EDIT + ADD (Manage) Genders 2. Options to EDIT + ADD (Manage) Relationships 3. Need to have for the custom fields type section. - Checkboxes - Drop Down Select Box - Multi Select Box - Radio Buttons - Date Selector - Multi-line Text Area - Number - Text Box - URL 4. Create an account - process: need to specify which of the entered information (first name, last name or username) will be shown to anyone else directly after account - creation. Or the account creator can decide which one should be shown in the profile. I wasn't able to figure out why I need a username when in the meantime my full name (first and Lastname) is shown everywhere. What happened to the username?! let the user define which one should be shown in the Profile, User name or Frist Name & Last name or an option to shorten the shown surname for others to the first letter. 5. Banning Username (e.g test, boobs, pussy, sex, Sitename(if admin then allowed)), better to have the option to ban words in the Admin panel 6. Accept or decline an invite for a group (right now the setting seems to be as soon as somebody invites somebody in a group, you become a group member instantly). need to provide details of the customization. And have to use COMMENT beginning and at the end of the code. Also, need to provide a list of the files has been edited including line numbers. Above mention issues should be also manageable from the admin panel. Also a detail instruction, how to adopt these with the new releases of the Script. My suggestion will be to create plugins. I am looking forward to your reply. Best regards
