Young Gun Marine needs engine build

I am a relatively new marine, graduated boot camp in April. My project is a 70 swinger I've had since I was 17. Currently had a /6 but I have a 360/904 combo that need to be built. I am stationed in camp Pendleton, ca. However I'm from the sf Bay Area, near Santa Rosa. I know this seems kinda pathetic but I have no idea the extent of work they need to be ready to run. All I know is that the engine is not frozen. Hey I got the pair for a total of $195, I figure I any go wrong!

Basically i wanted to reach out to the local mopar community in hopes there is someone near my home town that could be put me in the right direction to gettin my engine and trans build on a tiny budget. Maybe someone knows or owns a shop that could do the work cheaply. I have a very mild build in mind, want to make the car daily driver quality so fuel economy is somewhat of a concern to me.

I appreciate any help I can get. Thanks in advance!
