Front bumper damage, next steps?

Have only been driving 11 months and had a collision at about 2-3mph getting off my drive. The front bumper is quite cracked but I can't see any damage to the lights or tyre thankfully. Just wondered what the next steps would be - take to a garage, a body shop etc? Absolutely beside myself and also worrying that there could be damage underneath (partner says it's unlikely but I don't know anything about cars). It's a Mazda 2. Any advice would be massively appreciated!
