Hey Fred and Ed,
don't be discouraged, you are both doing something awesome!
Perhaps it might be helpful if you did it all in MS Excel or an equivalent spreadsheet program that you are familiar with. Things are really hectic here, and normally I would just generate one but all you need is a column with the list of names another column next to it with a list of user names and a final column with the number of tickets sold. From this you can manipulate the data etc
If this is a little to tricky for you you can type out each name down a single row and repeat each name for each ticket sold. then use
RANDOM.ORG - Integer Generator to draw random numbers!
no fuss no muss easy peasy Japanesey!
