There multiple ways to do it but I would recommend to keep it as simple as possible. You have two easy options to achieve this -

1. GLBP (Gateway Load Balancing Protocol - For more info on this Plz visit this link

2. PfR (Performance Routing) - Config of this one is bit tricky but this could be the best option to Load balance traffic on multiple WAN links. You can read more about this here

Please let me know if you need any configuration related assistance.
