That's not a "deal"... and not how things work in real life.
There'll be negotiation and both the EU and the UK will get less than they want. There'll be free trade for sure, ironically there'll most likely free movement too.
More importantly, the UK will get less than they currently have. There's no possible way a new deal is going to be better than the already very sweet deal they currently have. A fair and reasonable deal will probably be something like that Norway and Switzerland have, which is very similar to what the UK currently has, but loses them their vote in the EU, and doesn't give them most of the things the Leave camp promised. A deal that gets them everything the Leave camp promised is impossible.
It is possible that the UK gets a slightly better deal than what Switzerland and Norway have, because the UK is bigger, but it's still not going to be a lot better. Certainly not in the current climate.
