   I often have a similar problem, but I want to use resistors that we   
   have in stock. I have a program that lets me spec the resistor ratio,   
   sizes to use, and range of Thevenin impedances.   
      
   The program does that for two resistors. More complex stuff, I Spice   
   and fiddle.   
      
   After it lists all the solutions, I prowl the schematic to see if any   
   of the values are already there, or if I can swap one. So I wind up   
   with 7.87K logic pullups or something.
