Need Chrome Addon Extension built to do browser Automatisation. Java script codding needed

Hi there, i need someone who can create me Chrome Addon (extension) which could do the job. Its probably JavaScript coding. First of all, when i upload this Addon on to Chrome, it must go to website, to login to the website. I enter login/password and captcha. Then it must go to my selected website and keep refreshing it for 30-50seconds until it see number 1 or more, instead of 0. When number 1 or 2, or 3, or 4, or more, appears, this script should click the button Select All, then Add selected items to basket. Once items added to basket, Addon has to go to basket, select all items, and click Buy All. (from account balance). Then go back to cart, click button Empty Cart, and then do same job all over again. Website will work on ONION (TOR). So addon do the job: (1).Go to my selected website Login page, i enter login password, captcha manualy. (2). After login, Addon go to selected website link and keeps refreshing it until he can see number (1) or more, instead of 0. (3). When its 0, ADDON should just keep refreshing the website for every 30-50seconds once it see number (1) or more. On every page, there is OK button popup coming up, so Addon must click it everytime. (4). Then popup button "OK" pops out, addon should click it. (5). Then select all items and Add to Basket. After items added to basket, click OK button, and then click Buy All. (6). After items bought, redirect to cart page, click OK button, and then click Clear cart. (7). And then all over again, do the same job, go to my selected link, refresh it until Addon see number (1) or more. And then again, click OK button, add to Cart, click OK, go to Cart, click OK, select all items and click Buy all. (8). And then again, go to cart, click OK, clear cart, and go back to step (2) to continue do the job.
