I have been away from the hobby for a little while and am not as confident in my selection abilities. Does anybody have any suggestions for a provider that:
A) Is preferably in the north metro/suburbs
B) available on short notice ie. asap

Hay babe I am in the north burbs. I am available form 8am to 10pm for In Call and Out Call 24/7

you make no sense how can you be available from 8 to 10 PM and 24 hrs

It makes complete sense.  She has INCALL available only between the hours of 8am to 10pm.  Outcall is available any time of the day.

I am located in the north metro as well, & can be available on short notice. Availability does of course vary from day to day. 9am-9pm, 7 days.

Try SweetSarah. She's a terrific, low-key provider I've seen many times, often with little lead time.
