Hi Anthony
Do you have your own ip blocks available with you ? or using the subnets given by the ISPs ?
if you are having your own ip blocks you can try configuring GLBP and have outbound load balancing.
I don't think you will get inbound load balancing as well.

Thanks for the Message, what I?m looking at is, The LAN traffic via this 2 router with 3 links should be equally load lanced and each should be back up to each other

When we have 2 different ISP;s, I would suggest for more controlled and filtered way for sending the traffic from 2 different ISP's.
I would suggest to use NAT and PBR (policy based routing).I would first look at the kind of traffic, users, applications that I have to go the outisde world. Once the traffic is determined I would see the traffic distribution of the users over the two links. I would use my application, mail traffic to go thorough one link and internet and other traffic to use another link.I will make both the links as back up of each other.In case of one of the link goes my all the traffic will use the other link. I would suggest to implement proper QOS and rate limiting to drop the unwanted traffic.
