أحتاج مبرمج PHP/MySQL لتنفيذ بعض التعديلات على كود RoundCube لتنفيذ صفحة تسجيل مستخدم جديد

I have a PostFix email server with MySQL and RoundCube (roundcube.net) as email web client.

I want to have a registration page for the RoundCube where user will insert below info:

1. Full name

2. Main Email address

3. Alias Email address

4. Secondary Email address (for email recovery)

5. Password and Password confirm

6. Invitation code

7. Captcha verification

On submit:

1. An invitation code will be checked

2. A new user should be created in PostFix mail server with the main email address and password provided

3. An alias email address should be added to the same user in PostFix mail server

Next, we want to create admin pages to manage users, invitations, profiles ... etc.

I'm looking for a PHP/MySQL developer with experience in RoundCube. This is the first task in a series of following tasks.
