Guys - how do you determine when to charge by the hour or by the job?? I'm assuming if it's going to take several hours to do a job you charge by the hour (I may be wrong) but I was wondering if there is a rule-of-thumb for this or if it's just preference? Also, how do you price the job when taking the square footage of a yard? is there a rule of thumb when charging by the square footage or what?? These may be silly questions but I'm just starting out and want to get an idea on how to charge when pricing jobs. Thanks in advance.
