I have a list of 15 people. Each person has between 1 and 3 entries in a lottery, for a total of 35 entries. I need to select 9 people from the list of 15--nobody can win more than once.
What is the most transparent, most random, most low-tech way I can do this?

Assume that the drama and stakes level are such that accusations of tampering are a possibility, and that 3-5 names and/or entries may be added or withdrawn shortly before the lottery. Both these things seem to preclude premade names in a hat. I want anyone who wants to, to see and understand as much of the process as possible.
I have access to a standard assortment of RPG dice.
My current plan is to split the entries into 3 numbered groups of 12 (with one or more "free" spaces) and have different unaffiliated people throw a d12 until 3 unique people have been chosen from each group. Will this work? Will it matter whether someone with 3 entries has them all in one list or evenly split between lists? Will it matter if all of the smaller-entry people are in the same group or not? I have a vague suspicion that things get more complicated after a few people are selected (and their entries thereafter withdrawn), but I can't quite see it.
