that would be a single speed but not a fixed gear. Either way with $300 its definitely doable.
replace
-wheels with some of the cheap formula/mavics that are always being posted $150
-get a track cog or a freewheel $20
-new tires, brake pads, cables, and housing, bar tape chain etc <$100
-if needed a new chainring $30
total $300 you can decide where you want to skimp.
