I really need B/W lands. Will trade extra value for Marsh Flats ($30)

Hello fine people!

I'm currently trying to solidify a modern B/W Token deck, and I really need the lands to fill it out!  My top needs are as such:
3x Godless Shrine
3x Isolated Chapel
4x Marsh Flats

I am perfectly fine trading extra value for the Marsh Flats.  Hit me up, and hopefully we can work something out!
