one of my past customers wants me to seal her driveway...it is in good condition, no cracks or anything.....although i have done this in my own home one time, i dont have a clue as to how to estimate this job.....i dont rmember how long it took me whn i did mine, not to mention the interuptions (kids) that made me have to keep stopping.....i know what the materials will cost me, but dont know what the "going rate" is for somthing like this.....anyone have any suggestions
