Designing bespoke or custom typeface for branding projects is rather huge project that takes time. How long does it takes to develop a full functional font? It depends on many variables. Such as character set, typeface type, opentype features and much more.  Usually it takes from 6 weeks for very rapid caps-only typeface (such as Puffin Cafe) to a full year for type families (such as Belarus Railway type family of 10 styles).
