Website Client Onboarding Automation

I'm looking to create a seamless client onboarding process on our website.

Requirements:
- User Registration: New clients should be able to create an account.
- Step-by-Step Guide: A guided process to help clients through the onboarding.

Ideal Skills & Experience:
- Experience in user onboarding experience
- Familiarity with progress tracking tools or systems (nice to have but not a must)
- customer care

Please provide examples of similar work done.
