Then simply intercept all packets addressed to whichever port/s the proxies
listen on, no matter what the destination address is, eg:
iptables -A PREROUTING -t nat -p tcp --dport 3128 -j DNAT --to a.b.c.d
iptables -A PREROUTING -t nat -p tcp --dport 8080 -j DNAT --to a.b.c.d
etc., where a.b.c.d is the proxy you want to redirect the user to.
Alternatively intercept the packets from the particular machine (I assume this
mobile user either has a standard static address each time she's on your
network, or else you use DHCP and can tie her MAC address to a known IP
address).

Never write it in Perl if you can do it in Awk.
Never do it in Awk if sed can handle it.
Never use sed when tr can do the job.
Never invoke tr when cat is sufficient.
Avoid using cat whenever possible.
