From B&H

Kodak Flexicolor (C-41) Fixer & Replenisher for Color Negative Film - Makes 5 Gallons $ 7.95

Kodak Flexicolor (C-41) Developer for Color Negative Film - Makes 1 Gallon $ 9.95

Kodak Flexicolor (C-41) Bleach Starter for Color Negative Film - 1 Gallon $ 13.50

Kodak Flexicolor (C-41) Bleach III for Color Negative Film - Makes 1 Gallon $ 26.50

Total $58.

Down side is B&H doesn't ship most of that. So you'll need a local source. Upside is the Bleach starter is a one time cost. Upside that's a lot more fixer then 1 gallon. Fuji makes a bleach that doesn't need a starter.

I'd also suggest checking the Kodak and Fuji hunt websites for the various tech papers. Just to make sure you're ordering the right stuff.
