Needing a new spoke and pedal cage means it's not mechanically sound doesn't it? Or do you mean it sounds like machinery?
and from the pics it looks like you've done fuck all work on the bike to warrant such a high price. the cables clearly need replacing and the rear mech/freewheel/wheels are filthy. at least do it up a bit before trying to pass it off on here. even if you have no idea how to fix up a bike, spokes and pedals aren't difficult to replace.
