Ticket drop checker / change detection / spinner bot

Looking for a bot to alert me when specified events on [login to view URL] have new seats available. This does NOT need to auto-purchase or solve captchas (but it's nice-to-have if you already have software that includes this). In your response, please let me know 1) whether you are offering pre-written bot software, or custom software for this project (either way is ok); and 2) whether you have worked on projects involving similar sites in the past. Also would like to work with in the future as superboletos does change its software from time to time. Program Requirements: - Checks user-specified URLs at [login to view URL] for new seats available, at user-specified time intervals - Alerts upon finding new seats (visual, email, and sound effect). It could be that an event goes from sold out to having some seats, or from having some seats to having additional seats. - Continues working when the computer's IP address changes, or actively uses a list of proxies - User must be able to test a working demo
