Recommend me a tube tester calibration service (Hickok TV-7)

I got a Hickok TV-7A/U tube tester which appears to be in need of calibration (octal tubes test way too low). From my research this is not something I can do myself - aside from being completely inept when it comes to electronics, I don't have the tubes with known values, which are required to perform the calibration. The only place I have found so far - alltubetesters - charges $180 plus the shipping charges. Not in the budget at the moment. Do you know of anybody - preferably (but not necessarily) in the Chicagoland area - who can perform a TV-7 calibration. Hoping to spend no more than a hundred bucks (and even that is a bit tough right now). Thanks.
