Potentially Moving

So, FH is in school full time right now and will be graduating December of this year. Currently we're living in Seattle, and all his family and most of my family are here in Washington/Oregon as well. We're not sure where we're going to be once he graduates--hopefully he'll be able to get a job here, but we don't really know how it's going to play out yet because we'll have to go wherever he gets a job, meaning we'd have to move in the middle of wedding planning... Our wedding is set for September 2020. We haven't put down deposits on anything, so we're not tied to having our wedding in Washington, but we'd rather have it in Seattle. If he gets a job immediately after he graduates, that would leave us 8 months to plan the wedding... Is that enough time to book a venue or plan a wedding in general? We're going to have a weekday wedding and the venue we toured recently said that our date probably wouldn't book up... How hard is it to plan a wedding from a different state?
