I've only ever seen traveling providers in the PF area, but there are some decent ones. Search reviews with US/Chicago but put in location as Plainfield (there are only a few), Naperville (a stones throw away), Bolingbrook and possibly Joliet(quality ranges from ok to god-awful). BEWARE though, only look at reviewed providers when looking in PF/Naperville. Dupage Co is notorious for Po-Po traps.
Worst case, call some providers that refer to their location as 'West Suburbs' and see if PF is in their wheelhouse. I've met with a few at hotels that are only about 15 minutes further East in Lisle so getting them to go a bit further shouldn't be an issue.
Hope that helps some.
SMEGMA!!
