I totally agree your statement that making a font is the easy part, design is hard. I had mounds of sketches and paper all over the place when working out my fonts. It took a long time to even get to the digital part.just to add to what the last poster said, the making part of typeface creation is a pretty simple process especially if you are good with the pen tool in illustrator. Typetool or Fontlab works well and i think they have a free trial you can mess around with.
the design part of typeface creation is extremely difficult and takes a long time to do well. you need to be working at both a micro and macro level and be highly attenuated to both to do it well.
