The last week in May will be Bluegill heaven in Georgia. I do not know of any guides but every lake in Georgia will be hot then for the Gills. There is a State park near Moultrie that is good for Panfish. If you are going to stay in that area for a few days you may want to check out the Satilla River. Maybe a member has a farm pond. ??
Good luck. I will be at Lake George Florida that week and that is the Panfish capitol.
