Some where I have a link for building a fluid bed. This is from another site but still good. I have bought all the items for one just haven't got around to putting it togeather. Think at the time parts were like $6 and bought them at Lowes's and pet smart had the pump already but that is a low cost item also. You might have $15 in it and much cheaper if you scrounge. Will find the link and post it here tonight if possible.
