That's WAY too much for a 30 gallon. I would go with 10 sails personally. No hermits.
+1 on this...I got 30 snails for a 105 gallon tank with dry rock and dry sand...not enough algae to support all those snails- lost 10 in the first month...I have ceriths, nerites and nassarius snails--all which I like due to the job they do on the rock, glass and sandbed...But if your tank is new, I would get around 10-15 snails. 3 different types so they aren't roaming the same area and competing for food.
