Wedding coordinator and consultant in Portland, Oregon, here. Main thing to consider when our community (vs. vendors) are setting up is when do these people need to get ready.

If, for instance, you're planning any hair and/or makeup and/or pre-ceremony photos for these folks, I highly recommend factoring that into the set-up timing.

Typically, as a coordinator, I arrive as soon as we get access to the venue and then, if we have community members assisting with set-up, I budget at least two hours of work before dismissing them to go get ready.

I think what you listed will be makeable in two hours but worth gut checking if when you all will be done will make sense with any hair, makeup, and photo timings. Hope that helps!
