I am studying architecture since 2008, this is my last year of study, and I am working in Revit Architecture since 2009, I can offer you some sample projects that I worked in Revit to see the detail level. I can provide you also renderings of the building if necesary to convince the client of your work, and also if you need to modify parts of the building that is not a problem.
I can provide you small projects like a house in 24h and big projects like dwellings, office buildings, in about 2-3 days, depending the detail level of the building.
Regards,
Mihai Pascalau [architecture student]
