I run something similar here in Greece, but have not noticed any 
performance problems just yet. You are probably getting a lot of hits!

What you need is an apache module designed specifically for speed / 
bandwidth throttling: www/mod_cband

You may also wish to have a look at these instructions (linux specific, 
but easy to adjust for FreeBSD):

BTW, what is your ADSL speed? You mention upload capacity of 500kb/s, 
and I suppose you mean kbits/sec, *not* kbytes/sec. Assuming it is 
kbits, you may well be consuming all your upload bandwidth if for some 
reason you get more than a few simultaneous connections...
