How can I revive a faltering town festival in two months?

[JosephT]

Our small town's annual fall festival committee is in disarray after the longtime organizer stepped down, and I've reluctantly volunteered to help pull things together for this year. The event is only two months away and we have a basic framework, but we're lacking fresh ideas and reliable volunteers for key roles like vendor coordination and kids' activities. I want to preserve the traditions people love while injecting some new energy to attract younger families. For anyone who has rescued a floundering community event, where did you start? How did you recruit and motivate a new team on a tight timeline, and what are some low-budget, high-impact additions you've seen succeed in making a familiar festival feel special again?
