automated id joiner

Im requesting an application that i believe to be done in .php and .js to be written for an online game I play. It's going to join accounts, that have a special id attached to them, into a 'raid' that has an attached id to it, and then launch it, all while inputing a captcha for each account. Basically integrating a captcha website service, which I will provide. I have some .php files that have had the php stripped from them and left the html(or plain text so to speak), so perhaps you can get a sense of what it should look like and can do. I have all the javascript that is necessary for one that i used to have, just dont have all the php pages. It may be required that you log into the site to get a better idea of what it is that needs to be done, but once you get a visual representation, i feel it could be a fairly easy task.
