What did you come up so far? It is hard to help out if you won't spell out what you already have. You need to specify how much you are willing to spend for this trip as well. Otherwise, you can start checking ITA using your preferred airlines and the number of segments you want to hop.

What you are asking for is to go from or near your home airport to a place in Mexico on or around certain days, this is called a trip not a MR. Now if you are asking for how to maximize your trip, look at the fare rules to see what the valid routing is for that particlular fare rule and segment your way there.
