I made arrangements to do a pro bono job, plus a money job(lot clearing), for a woman that is spoke person of the HOA. We discuss this over numerous emails in detail. She mentioned the price she'd pay for the money job in the emails and asked that I get started right away. Well, after I completed the money job(lot clearing) and the pro bono job, she stopped responding to my emails. There is no contract. She sent a contract via email earlier, but I made a few changes and she agreed. I signed it, and emailed the new contract back to her, she said she'd send it back signed. I went ahead and started the jobs before getting the contract back, and she never sent it back. But I do have the emails of her asking me to start with a promised amount. Can I do anything?
