For the mini bow tucks fabric requirements are:
1 yard for outer top, front pocket, ties, inner pockets and handles
1 fat quarter for bottom section and front pocket lining
1/2 yard for lining
1 1/4 yard fusible batting
I hope this helps you I'm in a similar situation for fabric. I also have to drive 40-60 miles to get to a fabric shop. It sounds like it'll be pretty.
