Rob Kardashian & Blac Chyna Start Negotiating Wedding Special

Rob Kardashian and Blac Chyna are all in when it comes to cashing in on their milestones as a couple ... and they're ready to start talking turkey for a TV wedding special.

Sources close to the couple tell TMZ ... they're on solid ground since Dream's birth, and want to get married next year. We're told there's no date set, but one major factor in that decision will be what's best for TV.

There's nothing contractually obligating them to shoot their wedding, but for the right price ... they'd be all about it. Remember, they scored a sweet deal for their baby birth special which airs in a couple weeks.

Our sources say Rob and Blac already have a few venues in mind, but they're not locking anything down just yet. As for Dream, there's no drama in the co-parenting dept and she's helping them grow closer.

Now an agent just needs to get 'em closer to a TV deal.
