Asterisk development for a callback project

I need an Asterisk programmer for the following modifications to a callback service : - Modify the creation of the call file to make it assign the value of the DID called by the users to a variable. - Install a range of DIDs (32 DIDs) on an existing destination in FreePBX, and explain how to do it. - Make my server receive SMS and create a call file when a SMS is received. - When I changed the password of the admin user in FreePBX, I lost access to many sections of FreePBX including the section “Administrator”. I need to get back the access to every installed FreePBX modules. - I need to password protect the access to the web pages on the server. - Create a new table in MySQL that has 3 fields. My server is running Centos 5.2, Asterisk 1.6 and FreePBX 2.5.1.1.
