Suggestions for blinds in 10 person tourney

[3rddegree]

Hello gents. Having a 10 person tournament(friends and family) and am looking for suggestions on a blind structure
We will start with 5000 chips with each person having an opportunity for a re-buy or add-on(not both)
Would like tourney to last about 3 hours
No pros here, just a bunch of novice friends and family

Any info or suggestions would be appreciated

Try the default blinds structure but with a longer level duration, say 15 or 20 minutes (or longer).
