How do I build this character? [closed]

I have an Idea for a Goliath character. Basically I want it to dual-wield lances without a mount and just charge in and hit with both weapons.
I’m newer to the game so I’m not so sure how to do this. I am Hoping to play a cleric. Is this even possible?
If a mount is a mount needed? If so how would damage for the charge work would it count damage for both lances in the charge.

It would start at 10 but I’d be willing until 15 – and I need to understand what feats I need to use to make this possible
