Outdoor Ceremony/Reception Same location - How to move from one to the other?

We were thinking combination of groomsmen/ushers, my drumming group, and some of the venue staff (small venue though, only a handful of people). It'd take them maybe 15 minutes to do it (maybe less) but I don't mass confusion or panic to clog up the works...

If you're having groomsmen, this sounds like a good job for them. After you "walk out" as a couple, maybe have the officant say something like "we'll have a brief break while our groomsmen set-up the chair at our reception location." I've never seen this done but at one venue I looked at there was going to need to be time to transition like this.

We reused chairs from the ceremony for the reception. Here's how we handled it:

We had a "cocktail hour" in between. The cocktail hour set up had a few high-top tables and a few low top tables with some chairs (~20) to accommodate the guests that would not be able to stand for 30 minutes at a time. During the CH, a small team of people moved 102 chairs from the ceremony to the reception location. If the guests were paying attention, they could actually watch the whole process (since the CH location was in full view of the ceremony site) but, well, I didn't care. (It would have been an additional $610 to rent a second set of chairs.)
