It's hard to say what I would charge for a wallet like that one, because each customer is likely to want something a little different. If anyone is seriously interested in working on a project like it, just PM me. I also have a very limited supply of nice selvage denim from mostly Samurai jeans that can be used for projects like this one if anyone is interested.
There are more pictures of everything here: www.flickr.com/photos/hollowsleather The mid costs $150 base price. The one pictured above is an orphan, and it's available for $125, ready-to-ship. No wait time.
The price typically includes shipping in the US, but unless you're ordering something very large from very far away, I only ask for $5 to cover international shipping. I've put pictures of a handful of recent projects up: More here: www.flickr.com/photos/hollowsleather
Here's the whole ensemble of pre-made items that I have right now. The two darker brown seat bags are $85 each, the saddle tan one is $110. The belt measures 34.5" from the middle hole to the end of the buckle (compare it with yours) and it is $50. Nice textured brown with solid brass buckle. The mid-length is the one with the six-slot interior, and it is $125. The last piece is a cigarette case, fits a pack nicely. $35. Message me if you're interested.
