Illustrator needed to graphically represent children's orchestra concerts

I am the Vice President, Marketing & Communications for the Buffalo Philharmonic Orchestra in Buffalo, New York. We are seeking an illustrator to help us graphically represent four of our kids concerts -- one Halloween concert we call 'Symphonic Spooktacular,' one Christmas concert we call 'Jingle Bell Jam,' a concert for our youngest listeners we call 'BPO Little Kids,' and another spring concert entitled 'Dan Brown Wild Symphony,' which is a package show, the site for which is here -- https://wildsymphony.com/. We would like to find someone who can create something similar in style to the image attached.
