Need To Add One Musician/Singer to Well-Paid Extended Gig (Columbus)

I need to add one singer/musician to a Chillicothe folk band for a two-month gig. We play mostly original songs, some classics. We have an extended engagement at a southern Ohio theme park 8/30/25 to 10/26/25. It's weekends only, every Saturday and Sunday, plus Labor Day, but not 9/6/25. 18 show dates total. It's three or four half-hour sets/day. It's pays $200 per person per day, plus tips, so a total of $3,600 plus tips over the whole run. Tips can be good there. I'll be playing guitar, so I'd rather you play something like upright bass, banjo, fiddle, mandolin, accordion or something else. As a singer, it'd be great if you had both lead and harmony skills. Folks with pro, or close to pro, or at least advanced, ability would be ideal. I am very dependable and would love it if you are too. This is a good gig. The band is Toadstool Shadow at www.toadstoolshadow.com.
