Contact sort app

[AC Question]

Very Frustrated. Tried 10 different apps and can't find one that does the following. I had for my I phone but can't find one for Android..
Looking for an app that will allow me to sort my contacts by the following.
Groups then sub by company then by individuals. Not Group or Company or Name.
Example
Engineers
- ABC Engineering
- Bill Black
- John Doe

Interior Designers
- Great Design
- Jill Johns

Reason: I have 3500 work contacts in my database. I have them broken out by the above for ease of finding.

Thank you.
