Sorry it took so long to get back with ya, for some reason I missed this reply to the post.
Back in 2010 when I did this it cost me roughly $7.50 per sheet to have printed a local printer in the DFW area. I am sure its a higher cost now, but would be worth the cost to have done as an extra item.
I remember also seeing a YouTube video where someone did them at Staples or Office Depot type place had them printed on the card stock, used a high quality glue and did them kinda like a DIY kinda project and cost them way less if you wanted to try that route to see how it would go without breaking the bank. There are several card templates to download on the internet to use in photoshop.
Hope this helps.
