Webinarjam setup with OBS for online webinar

I am looking to set up a WebinarJam webinar with OBS streaming for my online webinar. Having done some research, I am confident that WebinarJam is the best platform for what I'm aiming to do, while using OBS allows me to do more with the presentation. The webinar is expected to have around 1000 viewers, so I'll need to make sure everything runs smoothly. I am hoping to find someone who has some experience with these two platforms and webinars in general so I can get the best outcome for my project.
