This is a two part question: first regarding liening a property seek payment for work performed and second about my ability to seek damages for lost earnings against someone who is trying to prematurely exit a construction contract. I have an executed construction contract with a customer. I began preliminary work on the project (tree removal, dirt work, obtained permit, window and door review, etc.). Then the original bank came back to the customer with an appraisal much lower than contract value. I recommended another bank for the customer to use, however they decided to go with another bank - Iberiabank, which required a lot of personal and financial information from the builder which I voiced displeasure with but told the customer that I would be happy to jump through any hoops if this is the bank the customer felt strongly about using. At this point the customer told me that they wanted to put the project on hold and asked me to send them an invoice for my work completed to that point. I sent them an invoice (~$6,000) for the work that had been preformed on the property as well as my time. They responded to this email that they would not pay my invoice until provided with detailed subcontractor invoicing and that due to my unwillingness to work with Iberiabank (not true) that they desired to cancel our contract. Up until this point our relationship had been very cordial. I believe they have found another contractor that offered a lower price and are trying to find a reason to cancel our contract. I would like to know my best course of action to 1) receive payment on my invoice 2) seek any damages for an early contract exit - this was a significant project and potentially represented around $100,000 in profit
