Check for update

Hello, i would like someone to help me to make this:

I want to make 1 php file to include it in my website to check is the users using the latest version of the site:
Example : <?php include("updatecheck.php"); ?> , this file will get information is the user using the latest version of the website. To Display the message if there is New Version Avalible in POP-UP message where to has :
- 1 Menu for Changelog
- 1 Butoon (img or text) Download - when they press it to download the files
When Press the Button to display them "Loading Process" that shows how much &#37; is downloaded (like you install a game you see loading process the same thing)
When they click on the "Changelog" to pop-up a window where to show them the changelogs . To get information from the file "changelog.php" (from the server). If its posible to make it like this here : HERE click on "Estable: v5.0.0" to see how to display it.

Server Side:
- changelog.php (where i will put file updates log)
- version.php (where i will put the version of the updates, if i put version 0.2, users use 0.1 so there is new update avalible for them)
/download (the folder where i will add the updated files, where users will download them, to download the files in the same folder to replace the files with the new ones)

If this is big job i can pay for the little help for making this, i dont have much money but i can give 5$ for this system
Thanx

Hello diablo21,

I have moved your thread to the Project Requests Forum as this is where any question like this should be asked.
