hey, no, sorry i dont know of any i could recommend but depending on what kind of object/repair is required i highly recommend someone who is certified by the AIC. heres their web site......

They are located all over the USA so it should not be hard to find one close, particularly in alexandria va. For instance, i am now located in Charlotte NC and i was interested in repair of a colonial paint decorated dower chest and found this guy through AIC.

A laboratory, they can tell exactly what they are dealing with as opposed to just guessing. This is really important if a wooden object is painted. my 2 cents
