How do you find matched components?
Why did you chose the particular values of 10 k&Omega; and 3.6 pF?  Why not chose a resistor or capacitor value up front for which there is another standard value at the 2 or 1/2 multiple?

3.6 pF is very small, such that parasitic capacitance will likely be significant.  You're not going to get a reliable 2x anyway.  In addition, capacitors aren't that accurate to begin with.  When you don't specify, ceramics are usually 10%.  You can get 5% for a little more money, but after they get scarcer and more expensive.

Since the capacitors will be harder to find in particular values than resistors, I would start there.  I would also make the smaller capacitor big enough to get well enough above the parasitic level so that it's value will be reliable when in the circuit.  47pF and 100pF sound like a pretty good combination.  That would require a 753 &Omega; resistor, so a 750 &Omega; 1% resistor would do fine, with the other value being 1.5 k&Omega; 1%.  Note that your values of 10 k&Omega; and 3.6 pF were off by 1.8% just from the nominal part values alone, and considerably more due to parasitic capacitance and part tolerance.
