Easy enough to add air handlers and outdoor modules later if needed, or rearrange air handlers to suit future remodels.
Efficient, quiet, zoned, and completely variable capacity.
Oh wait, the OP is to cheap to even hire an engineer, so the extra up front cost of a VRV system is right out...

I would take your plans to the engineer and have him calculate the heat load and plan the equipment. Give the new plans to the contractor and let them bid on the job. The contractor is used to calculating heat loads based on maximum outdoor temperature. You will be running mainly at night, which is going to decrease your cooling load as compared to the afternoon, but also complicate matters when the outdoor temperature is not that high.
Letting the contractors guesstimate the load and then basing the equipment on that is gambling your money away.
