Hi Anders, I can second what Lara said about building a scenario. I also built a scenario of a city of around 150.000 people and the time investment was about one year. Currently, I am preparing it for release which also means getting it re-validated with current sumo versions.
While the conversion, adaption and validation of the road network may be tedious (highly depending on the quality of the OpenStreetMap data for your area), I found the generation and validation of the traffic demand much more challenging. Think early on about what kind of traffic you need and what input data you have for it. Lara's papers give a good intro, if you plan to use the ACTIVITYGEN approach. But in the end it really depends on the data traffic data you have about your city. So if you like, you can put me on CC for your mails. Maybe I can contribute some aspects, too.
