Local business needs software consulting services before build wrong thing, preferably in Minnesota

Hey ppl, I run small bike repair class near Midway, teaching teens basic fixes with worksheets and phone vids. Couple shops asked if we could track lessons online, but I dont wanna blow cash.

Looking for software consulting services to decide: portal, app, or just better workflow. Need feature plan, rough cost, timeline, user flow. Any team from Minnesota/Saint Paul is welcomed, but we can work online too

What helped you, and what was pricey noise? Thank you:)
