Krekeris,
There is a bus company, Caminante, that offers an hourly service from Toluca to Mexico City's Airport (between 4:00 am and 8:00 pm.) and from there you'd need to take a taxi to you final destination (there is another schedule-restricted service). The cost is the equivalent to $10.00USD. Unfortunately the toll free number I have is 01 800226 46 27 valid if dialed in Mexico (if you have a friend in Mexico he/she can get the information you want). You can try dialing from the US 011 52 722 219 50 07 and find out schedules according to your arrival.
Don't believe me, but I've heard that close to the airport walking about 600m. (1,800 ft +/-) some people go to a taxi base ("sitio crucero del aeropuerto") to board their taxis to Mexico City.
Sorry for the short info.
