Similar to How Much Does a Logo Design Cost, giving time-frames is tricky. I like to allow about 4-6 weeks for a typical project, where the budget is around £750 - £2000. Sometimes I'll get it done in 2 weeks, and other times it's a challenging project, and it goes on past 6 weeks. Sometimes I've thought of an idea practically overnight, and other times it's just been a really challenging project which seems to take forever. If the the work is a larger Brand Identity project, then this will always take much longer than just a logo design. Usually at least 2 months work for a decent size Logo and Brand Identity Project: Logo Design, Stationery Design, Brand Guidelines, Website Design etc. It's also highly dependant on how many times a client says, "No, I don't like that idea." If each idea I present is met with this, then clearly it's going to take longer than if a client likes an idea earlier on in the project;This is somewhat out of my control. I NEVER promise that a logo will be finished by a certain date, but I will always try my best to complete a project as soon as is feasibly possible, if it is urgent.
