Posted job lost details

Hi I posted a job a while ago and had correspondence with a bricklayer who had a look at the job however I needed some engineering calcs so took the job down. I can now progress with the work but can't fined the contract details or chat with the bricklayer. Can you confirm how I can locate the correspondence and get back to the bricklayer who was Dave Appleton trading as DA Brickwork in Cornwall
