Hi there, I'd like to do what these guys do on their home page as far as scheduling goes: [login to view URL] See how you are able to click on any of the times to schedule a time to book an appointment? Pay special attention to how a pop-up with a scheduling form shows up on the same page WITH the time of your choosing? This "app" was built on HubSpot, but if you look at the code, I think it's Javascript-based. Bottomline, I would like this built. The exact same setup. The info from the scheduling form needs to be sent to my email, but I'm sure that's the easy part. Here is the challenge, I need you to hook this up somehow with my Google Calendar so that people don't double book accidentally. There might be some logic steps to it so that it retrieves ONLY the available time slots from Google Calendar and shows them on the front page—always reflecting ONLY real times available. Code needs to be clean so that anyone can pick it apart and make changes. Who knows, maybe I could end up rehiring you for some long-term work and you'd want to work on clean code ;) Aside from that, here is a page to study out at as well. Aside from the times available, people should be able to pick a time in the future, like on this page: [login to view URL] Time intervals between appointments need to be 1 hour 30 minutes. I have WordPress-based dev site you can use to run all your tests.
