In addition to cost, I would think that you would be spending much of your day preparing and eating food. I would recommend muscle milk shakes between meals. 1 scoop and 10 ounces of milk is all you need. I'd recommend coconut oil and hemp oil for good fat sources. Some more fruit (low glycemic index) may be a good addition as well, as your diet seems awfully low in carbs.
Perhaps I am out to lunch, as I am not a bodybuilder.
Hope that helps.
