You might want to start by reading some of the info at lartc.org. I'm 
afraid some of it is seriously out of date - but other bits are very 
much current. I started with the HTB script from this page:

http://lartc.org/howto/lartc.cookbook.ultimate-tc.html#AEN2241

and then further adapted it to suit my needs. You will most likely need 
to use different classes for different client IP addresses - and set the 
rate (and maybe the "ceil") option as needed for each class - in order 
to only allow it as much bandwidth as you want it to have.

If you need to add and remove IP addresses on the fly - you might need 
to "complicate" the script a bit further - but if your clients use 
static IP addresses - setting up few classes and filters for few clients 
shouldn't be too difficult.

Hope the above helps
