The helium molecule is quite small and mobile. Your best bet is to use a balloon material that's fairly impervious already (i.e. mylar instead of latex). Failing that, there are solutions that provide a protective coating on latex balloons to help them retain helium for a longer time. Ask at your balloon shop if they use anything like that. (One brand name ... not endorsing, just mentioning; it's the first relevant hit that came up on a Google search for "latex balloon coating" ... is "Hi-Float.")
