@jimp:
That link is for load balancing servers behind pfSense – meaning one external IP address, multiple servers behind the firewall.
What you want uses multiple WANs/external addresses. In that case, the balancing would have to be done via DNS RR type records or some other means (external load balancer, BGP, etc)
Thanks

How I test Load Balance ?
