Some of the best vendors provide content that works with: DAZ 3Delight, DAZ Iray, Poser Firefly, and Poser SuperFly. I've no doubt they sell more as a result. Providing OBJ and even a Vue VOB file would be "icing on the cake" there, if for example you have a large prop-based scene. A lot will depend on what you want to sell, and how good you are at making it, and where your passion and imagination is. Possibly also how good you are at research, in terms of finding out what's already out there and thus not trying to "re-invent the wheel". The obvious option for making content is fairly saturated: Walmart clothes on dial-a-clone gals. I guess they sell 20 copies or so, but I doubt they have much shelf-life. That said, there are relatively few really good total "I can't believe it's La Femme" makeovers for La Femme, and at the present moment she could use a few more tailor-made outfits.
