Planning help!

So I am pretty sure we found our venue! Heritage Hotel in Southbury.
It’s cheaper than all the rest we looked at & still gorgeous! We’re also choosing to get married on a weekday because it’s significantly cheaper but now I’m starting the budget on all the other ins and outs & I’m stuck!!
What is standard $$$ for hair, make up, photos, dj etc? I feel like I’ve been so focused on keeping the venue costs down that now I’m going to end up still over budget with all the extras..
