She pulls up in the middle of the street while I'm at a customers house laying mulch. Older lady probably in her early 70's, she wants me to come cut her lawn up the street. She was just sitting in the middle of the road and holding up traffic and I gave her a business card and told her to call me. She calls and tells me on my voice mail she is moving (red flag), she will be leaving town this weekend (red flag), and she wants me to go ahead and cut the grass while she is gone and she will probably pay me (probably?) when she gets back on Monday or Tuesday or Wednesday. I went and looked at the house and the yard is absolutely trash. Half is very new seed under an improperly installed erosion mat and the other half is jungle like. She told me to cut the grass and clean up the yard. We haven't discussed price, and I couldn't say 100% that she even lives at that house. I haven't seen her at the address and my only contact with her was for about 45 secs in the middle of the road through the car window and the voice mail message. I feel like I would be a fool to do the work with out first discussing price and walking the property with her to determine what needs to be done. Should I go ahead and do the work and assume she is trustworthy, or just explain to her when and if I talk to her that I don't do business that way. If I did a full clean up and mow on this property it would be at least $150-$200 and I don't think she would be expecting that. I'm thinking she has the lawn boy syndrome and wants to pay me $10. What do you guys think?
