Iowa City area consultant to cover for me when I am away

I need to be able to provide to my customers a contact person who can cover for me when I am unavailable in the Iowa City/Eastern Iowa area. I also need this person to come on site to meet and greet one customer in particular who has an installation already in place. Any hours would be paid by the customer.

I need to be able to provide a name and number by August 24th. The meet and greet may not have to happen if the phone conversation goes well.

Thanks In Advance!
