Are there any costs associated with getting a proposal and quote?

Generally, no, this is a service that I provide free of charge. The exception to this is where a client is not yet clear about the project brief and would like me to assist in gaining clarity about scope and objectives. In this case, the client may want me to talk to some other stakeholders and it might require more than one meeting to nut out the details. In this case, my time will be charged.  Commonly the cost is simply built into the proposal and quote if we agree to go ahead.
