PCBA Time Estimation Formula

I am looking for a good way to estimate assembly times per board. We currently use an engineer who looks at the BOMS and gerbers, but are looking for an alternative. Any formulas or software recommendations would be helpful.

Is there any way you can change the speed of how fast the head moves when placing a part?
