You have the right equations, so just solve. The assumption is that the lifting is done at a constant speed. What force does the lifter apply?

you need to convert feet to meters, 1 foot = 0.3048 meters. Then just apply your equations.

Well I know that W=fd. I have d but not f and I know the equation for f is F=ma, but I don't have a. It seems like I'm going in circles..sorry, I take forever with this.

The force needed to lift an object at constant velocity is equal to its weight ;), you DO know the force!
