In case you haven't found your solution yet:
My favorite online DVD/CD duplication/replication service is www.mixonic.com. It's very user friendly and you can build the entire project online (including uploading the media). They have pricing for anything from 1 day to 10 day turnarounds.
Hope this helps.
I'm not sure if you're into this, but I use www.createspace.com It's free and they'll send you a free sample of your finished work. It costs to buy more DVDs, of course.
You name the price to sell the DVDs too.
I am sure you've find some CD/DVD replication provider , but I'll recommend you must try www.CDROM2GO.com too for your DVD, Blu-ray or CD Duplication and disc replication need's. They provide professional, reliable and on time disc duplication & replication services as well as the supplies and equipment to do it yourself.
We just finished a dvd replication job for our summer camp video from New Cyberian in San Jose, CA. I must say the quality was simply fantistic and the customer service was also great. I got burned from a company in San Francisco that copied our ISO file as data without converting it to DVD-Video and blamed on us without specifying it. Fortunately the folks at New Cyberian was able to rectify the problem for us in a very short time.
My experience with cd/dvd copying is not to give orders to so called big companies. When they are big they will need more time to manage their staffs and there will be less time to manage your order. Just my two cents.
