Well I worked for $3.75 an hour yesterday less if you factor in diesel and a few other consumables
First mistake: Took on an interior house painting job over the phone.
Second mistake: Agreed to a price - sight unseen based on client's description of the scope of work and what another guy quoted. Said, I'll do it for you for that!
Third mistake: Client is a friend.
Status: Client's comprehension of scope of work and reality are not in the same universe. Abandoned balance of job and recommended client call the other painter to come and finish the job.
Not sure if client is still a friend
