Havoc boats are a good choice imo. Look on microskiff.com. Thereís a guy that has a towee calusa for sale in Austin. It has a mercury jet drive. Itís a good rig for running shallow rivers. Itís a fiberglass boat, only downfall is itís fiberglass. If you could find a decent aluminum mod v jon boat and a jet drive, that would be optimal imo. You might want to check Gregg Orr Marine in Texarkana. Tunnel hulls might be an option with a jet drive. Thereís a lot of variables when trying to run super shallow. Jack plates, tunnel hulls, loss of horsepower on jet drives, etc.
