Hi there, I am just starting out as a freelance proofreader and copyeditor and I was wondering what to do about my terms and conditions. I can write them, and I have had inspiration from others, however I am unsure about one thing in particular. Say, for instance, that I quote 3 hours for me to complete work that a client has sent to me. They have signed the contract and posted it back to me, and I have started work on it. If, nearing the end of my time limit, I haven't completed the work, is it legal for me to email/phone the client explaining that it will take longer, and so a bigger fee will be required? Will a reply on the email suffice? The only reason I ask is because posting out a new contract will take ages, and by that time, the client's deadline may have passed. How do I go about this? Also, sorry for all the questions, if they would like to pay by cheque, is it mandatory that the cheque has to clear before we start the work? As I require a 10% deposit before commencing any task. Thank you in advance.
