1999 Volvo C70 Leaking Coolant

I got a low coolant light and replaced the coolant fluid, but a day later got the same red light that I was low on coolant. I looked and I'm losing coolant. I was in a fender bender on my right side the same day (not much of an impact), but wondering if this could've cracked something to do with the coolant system? What kind of mechanic should I take it to for a Volvo (I don't want to go to the expensive Volvo dealership) and how much could this end up costing? Thank you~
