I took on a huge Azalea job. I bid it for 10 hrs at 60 per. We worked 12 today and it's 50% complete. I've had the customer for a while now, so I feel I can admit my mistake if need be to get this corrected. Still, I must renegotiate this before I loose my tail. I need some constructive renegotiation tactics from some of you. Now that I've taken more time to look over the job I bid it at a 3rd of it's value. How should I proceed with this? I also need to add that We ran 2 Echo SHC 210 Power Sheers for those 12 hrs. So I didn't half step w/ equipment or manpower.
