HELP!! Edging pricing

[EmeraldLawncare]

HELP ME!!!
I got a call for an estimate on a residential property. They wanted to know how much I would charge for edging of their property. I measured it, and it totals out to be 521 feet. I'll be borrowing a gas edger, but havent ever dont it before. I have NO idea what to charge.

Any help would be appreciated

depends on how bad the grass is grown over the curb. if its not bad probably about $50
