Those negatives should work great.

If you are in a reasonable sized city, you can get presensitized PCB
material, developer and etchant from an electronics parts store.

Whatever you use to expose the aluminum sheets used for newspaper
printing will probably work very well for exposing the presensitized
PCBs.  Follow the instructions (maybe inside the package) for the PCB
material and do a few test runs to get the exposure/develop/etch times
right.

Have fun!
