308343 Scalix W/ Portal integration

We have a portal based on PHP and MySQL we wish to provide members an email address so there will be a link where users can click, they will put the ID they want for their email, clicking CHECK will connect to Scalix mailserver using the API (documentation attached) if available then will allow him to put a password and first/last name to create his email account on scalix mailserver. Task should require the attached skills. what we need to accomplish is "Automate user management" If you have any doubts ask me via PMB Thank you
