depends on the size of your operation.. large ops tend to buy more cheaper leads for the masses when smaller tend to buy less "better" more expensive. in the trenches with a dialer ive seen people max 1000 calls per day and average 1-2 submissions per day. grinders.. ratios are more important imo. out of those thousand calls they may have only connected 250 times and only spoken to so many business owners.. about 6 apps sent out per day to the grinders too
