First of all, it should be placed in a precoded file I have (a site page). Here's what it should do. It will be a page with a link in the center which should say <After voting move to next topsite> and would move you to the next page if you have pressed the image which should be placed exactly under the link (center). If you have pressed the image (note: when you click on the image, a new window to a link should be opened) and 8 seconds have passed, you can click on the link and another image will appear (pointing to another URL of course), another one and finally the last one (that's 4 images). Note, if you click to the link before you have clicked on the image (or before 8 seconds have passed after clicking the image), a small pop up should notify the user <Please vote, you cannot proceed without voting>. After you click on the last image (same rules for all the steps, you have to click and wait at least 8 seconds after the click) a new page should be displayed by the script, the proceed link should be replaced with a text <Type your In-Game Account ID here:> with a small box under it in which a user is capable of typing ONE username (16 characters long max) and pressing a button which will execute the following mysql query (if the login is correct and exists, otherwise, user should be notified that the username does not exist with a pop-up and have the right to type it again) <UPDATE accounts SET isVoter = 1 WHERE login=<<here is what user typed>>;>, there should be a time limit (60 seconds), if user does not press the button within 60 seconds, he should be notified <Your request timed-out, vote again>. After user have completed this successfully, the last page should say <Thank you a lot for voting> and place a cookie to check that he's not capable of doing the same process again for the next 12 hours.
And a small note, the code should not be visible (I mean, if someone try to download the file, he should be unable to view the code).
Our budget is rather small, so we will consider low deals. Project should be completed within 2 or maximum 3 days.
Links/Images/The code it should be placed in and/or any additional info will be provided after picking up a bidder. Thank you a lot.
PS: I have attached an example. Text is just an example..
Oh, I forgot to add this one, script should NOT be exploitable, I mean users SHOULD BE UNABLE to access the last page if they have not completed all the other steps.
