I was hired to fill in a swimming pool and level the yard. After the initial rental of a bobcat and 2 truckloads of dirt plus the last 3 truckloads of dirt and 2 days of rental costs for another bobcat. Between these I used my own money to buy more dirt (approximately 10 truckloads) and rental of a bobcat for 14 days. I have asked the contractor for money but he keeps saying that the owner needs to pay more money. When I spoke with the owner he said that the contract was between him and the contractor and he can't discuss the funding with me. I currently have NO money to pay my bills and I already have 2 in delinquency. Can I file a mechanics lien on this contractor. Him and I don't have a written contract. This was all on verbal agreement between us.
