Bermuda grass

[PUREBAY2200]

Gonna b seeding my back yard with Bermuda grass soon, front has centipede from the contractor and 1/3 of back is also centipede but the back never really took and is horrible.
I have been using rye grass in the winter (seed in October ) past 2 years with great results.
But I want a good lawn for summer and that will hold up the high traffic with all the dogs.

My question is has anyone in here done this on a residential lawn.

I handle all the grass and field management for our high school football and baseball fields but that's a huge scale operation.

Just wondering if y'all have some tips for getting the seeds to take and how to help the grass survive.
I will b tilling up the entire back yard and adding sand , after I get it tilled up and sand mixed in ill start to slope yard for drainage and then level it off... It's not at all level now holds water bad and mower scalps a few spots.
The seeds will b spread first week of May. Weather permitting.
Thanks in advance.
