This might not exactly be what you're looking for but a couple of months back, my team was commissioned to film a concert and the client wanted DVDs of the concert to sell. Since it was a small quantity (30+) we decided to burn the DVDs ourselves and package them as it was about 40% cheaper than sending them out for duplication. We got the DVD-R discs from a local store for about $0.25/pc (converted to USD) and ordered DVD cases in bulk online for $10 for 50 pieces. If you have a good colour printer, you could print the covers yourself and stick them into the box, or you could send them to a printing store to get them nicely printed on glossy paper. (We opted to print them ourselves.) You can use Nero or Adobe Encore to design the menus and add chapter markers. Of course, the methods outlined here are extremely low cost and if you're looking for something more professional (like with DVD stickers), then I highly suggest sending them out to DVD printers for printing and duplication. Note that if you want your DVDs to be in 1080p,
you're gonna to have to use Blu-ray Discs which cost more. Time-wise, burning the DVDs yourself shouldn't be too time consuming as it takes about 30 mins to encode a master copy (with all the menus and chapter markers) and about 5 minutes to duplicate each disc. I hope this helps. All the best for your tour!
