I'm currently on a full-time gig as a Search Engine Optimization producer (SEO) at Cars.com, which I joined in 2004.
Also at Cars.com I've done some some technical producer and user experience work, including a comprehensive New Car Incentives offering. The product lets car buyers see a broad range of rebates, cash back offers, lease rates and special financing down available in their own locations on their chosen models.
Do I freelance? Not very often, due to my respect for having a day job. But contact me anyway about your needs and if I can't help, I can recommend a trusted colleague.
