Hi Ibrahim (again )

I do not know the setup of your LAN , since you have provided us only your internet edge routers but you can also think of the GLBP to share the traffic from your LAN to the internet.

GLBP is similar to the more common HSRP and you can find more info to the next link

If you want to load share the inbound traffic (from the internet to your lan) you could use the relevant BGP attributes to the public subnets adverstised to your ISP (i.e. as path prepend or med). However, this is sth that you have to discuss with your provider since many ISP override the assigned BGP attributes.

Hope that helps,
