On my last bulk I was averaging 5K+ calories a day. Granted, it was a bit much for someone who stores fat as easily as myself, but I just want to put things into perspective.
Although I must admit that I'm a fan of slow, controlled changes. I agree with 3000 as a good starting point. Try it and see how you respond, then adjust accordingly. If possible, take in the majority of your carbs around your training session, and try to get 200g of protein if possible, but mostly, just eat more.
