Do you have a plan as to where you can obtain waste fryer oil? That is priority #1.
Pictures of my processor and wash tank are at the beginning of this forum. I have a very basic set up which cost me around $250 to make, plus I had some materials lying around. Ball valves are one of the bigger expenses since I use 9-10 of them in my set up. I use the cheap HF blue pump which will be replaced with a much higher quality pump in my new processor (still under construction).
