Similar to How Much Does a Logo Design Cost, giving time-frames is tricky.
I like to allow about 4 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.
It’s just not possible to pre determine when you will discover the idea that the client will like, so to promise a complete date to a client is pretty irresponsible.
