Los Angeles - Reality TV star Rob Kardashian and model Blac Chyna are planning to get married within a year after their engagement. And now, the newly engaged couple are reportedly being offered a TV wedding special worth millions. "Pitchmen are putting together offers for Rob and Blac, according to 'big-time TV producers'", reports tmz.com. According to the report, the most lucrative path would be an episodic docu-soap (a documentary following people in a particular occupation or location over a period of time) leading up to the big day with $150,000 to $200,000 each per episode, plus another $500,000 each for the finale. Producer sources say wedding vendors hawking flowers, cakes, dresses and all related to the nuptials would also fork for integration deals. It was earlier reported that Rob and Blac would invite his sisters Kim Kardashian, Khloe Kardashian, Kourtney Kardashian, Kendall Jenner, and Kylie Jenner despite the family's rejection of their engagement.
