I need A script for my existing website -- 2

I need a script only where i want run mulitable instances I want scrap data from three fileds Username - Password - Email an email to the user and cc to me.. but its alreadsy got an installer package so I just want it modified, i dont want the user to ender db details, but the script to be installed, and every install placed in a directory and an email to the user and cc to me.. but its alreadsy got an installer package so I just want it modified, i dont want the user to ender db details, but the script to be installed, and every install placed in a directory the user would have dear name, thank you for signup etc, your login and password is and I would get a copy and I want to edit the email, so do an include if you want in a simply txt doc I also want it completing within 24 hours.. its not a huge project at all https://www/[login to view URL] if you can do one login form so it will redirect them to the directy where there interface is? I would just need to upload the script to you, its a live support customer service script with a windows client software to anwser chats# please make the install look good as it does now.. so your doing a login form which will log a user into which directory there version is? but I'll design the website, so the main reg form and everything needs to go into a directory like signup the login form also need a login error, if you can simply put that on the index page with the return login errors, then I can take that login code and implement it into my design, can you do a lost password? so it really sends the same login email to them? you could just use the same welcome email template, remember just do an include ([login to view URL]) or something with username code, password, and name if they click forgot email, it will simply send that same login email, but what if they change there password,? so the users same script will be placed into say [login to view URL] and 2 etc
