Jake i did some checking around and right now tandy has the Craftsman Oak sides for $3.99 a sq foot.....that is a good price...but the problem is that they only come in whole sides of 27 sq feet....$107. Again not to bad but for someone just starting out you only want about half that size so you can do your project....correct a mistake! And have some left over for arm guards and such.
There are a few more suppliers that i know of but they are here in the states and i have no idea what the shipping charges would be to Canada.
Springfieldleather looks like it has about average prices and you can order the sq feet that you need. Just look under leather...then tooling leather. I would give them a call and see what the shipping would be.
And there are a whole lot of videos on youtube that show you how to cut, tool, stamp, stain and finish leather.
Another thing...is you dont need to buy the starter kits. Dont get me wrong they are good....IF you are sure your going to get into this. Otherwise you only have some basic stuff to get started and if you do love doing it...then buy the tools you need as you go.
For a plain quiver....since you have a pattern....all you need is thread, needles, stain and a finish. You can use some heavy duty scissors for the cutting and a drill with 1/32" bit for the holes.
When you get to where you are going to do tooling you can start off with a simple swivel knife and just a couple of bevelers.
It is when you get serious and start buying all of the tools that it gets really expensive.
Heck man i have a hammer that cost close to $100 and a swivel knife that was $60!!!
