Where to buy good plants?

I want to plant a 54 corner pretty heavily and my LFS has almost nothing in way of plants. I have asked them to look into getting me plants before and they never got back to me. I would rather buy from someone who cares and has quality, variety and might be less expensive.
Haven't completed my plans yet, but so far I'm specifically looking for: Pellia on stone, Dwarf pennywort, willow moss, cryptocoryne parva, wavy ulvaceus, crinum calamistratum, giant red rotala, and probably some java fern, windeløv and maybe a smaller sword. Now that I write it down that seems like a lot, but like I said I don't have a set plan yet. I'm still learning and this will be my second planted ever. My first is a 6g and I'm excited to start a new one with so much more space!
Any suggestions?
