For a source of Type C fly ash, find a power plant nearby.

Type C fly ash is stored by the mile. If the finished product needs to float, harvest the cenospheres.

Make an informed decision about the fly ash. All Type C fly ashes are not created equal. I suspect you will find that the ones higher in Ca will work best for you. A reputable fly ash broker should be able to direct you to a suitable ash. Some ashes are known as pozzolanic (they have natural cementatious properties, owing to the reactable Ca content). There is a commercial mix known as Post-Crete, a fast setting cement based upon fly ash. While exact recipes may be closely gaurded, I believe a search on the internet will turn something up for you. This is not a new technology.

I'm curious- why would you need to use fly ash for constructing a concrete block wall? Usual reasons for using fly ash is as a cement substitute (we're talking about a lot of cement to make this economical), needing high strength concrete, or needing abrasion resistant concrete.

Using fly ash without known properties is probably a recipe for problems or catastrophe. Your best source of information would be concrete suppliers in your area; better if they use the fly ash you're planning to use. Some types of fly ash are not suitable for construction.
