I'd advise you not to use SketchUp for this. When creating organic shapes it's best to use solids [1], not mesh modeling. Otherwise your coffee cups will look like they've escaped from Tron.
Ashlar has a lite version of Cobalt, called Argon - a commercial license costs $1200 or you can rent it [2]. There's also an educational license for $200 [3].
A less costly program that supports solids is TurboCAD, at $500 [4]. I've never used it, but like Ashlar Vellum, they've been around forever.
