Subject:      random sampling question

I have a question I am hoping to get some help with:

I have a data set with N = 447 clients. 4 clusters of clients have been
identified. I want to select 15 cases from each cluster randomly selected to
be representative of the age & sex distribution of each cluster.
(The age range is 4-11 years. To simplify we are using age groups 4-7
and 8-11).

For example, for cluster 1 (N = 220), if there are 22 females aged 4-7
(10%),  then I'd like the sample of 15 to reflect this proportion (2
clients, rounded up from 1.5). If there are 110 males aged 8-11 (50%), I'd
like the sample of 15 to reflect this proportion (7 or 8 clients).

I am looking for some type of syntax to randomly identify these clients,
with the proportions in the population reflected in the sample.

Thanks
