I did Painting work for a friend owning a construction company. because he was a friend and needed work done immediately I didn't write up a contract. I do have messages and invoices clearly stating what work was done and what was expected. about 75% through the project I asked for a payment so I could keep up with my bills and I was given nothing. a week later I stopped doing work on the project because I simply couldn't afford to. as all the work was not finished I don't expect full payment but I would like to be compensated for the work I've done. since then he has ignored my attempts to reach him or basically deflects and says he will call later. is a lein an option in my case? or is there something else I can do? I don't have money to get a lawyer but I do need the money I'm owed
