I am available (due to strange teaching schedule):
Monday and Wednesday after 10:30 AM to about 5 PM Central
Tuesday and Thursday after 1:30 PM to around 5 PM Central
Friday, basically all day until about 5PM Central
Saturday, 9AM until Noon Central
Sunday, after 2PM. Central, just incase that wasn't clear.
Other than Wednesday, most evenings I can be available as needed or with prior warning. I just am not usually on line then. My wife, however, is very understanding if I am working on something (and she would include this.)
