First, I think you may be blending two topics. 

This includes: Tile, grout, thinset(chosen by client), shower pan liner, drain, tile installation, mud bed for shower floor, bathroom floor, concrete boards for walls, shower faucet and shower head (ORB), seamless glass door. 2- new toilet and hookups 3- double sink vanity white shaker with soft close. 4- granite counter top to match either the kitchen or the tile ( to be chosen by client) this includes a 4 inch granite back splash 5- bathroom package kit ( toilet paper holder, towel ring, towel bar ) ORB 6- exhaust fan 7- double under mount sinks with sink faucets and all hookups.

I'm looking for a blended return with all my investments of around of around 20%.

I've listened to a good number of the podcasts and there have been some interesting systems that folks have put together by blending different platforms and strategies to help streamline their businesses.  

It is also a blend of SF and Honolulu. 

Most kennels use epoxy/polyurethane coatings, as they are seamless, resist staining from animal fluids and can even be antimicrobial... not to mention cost efficient Material cost should be around .50 - .75 per square foot.

It’s got to be one or a blend of several of the items on the list.Thoughts? 

We coordinate all our activities to insure the acquisition and renovation services run smoothly in a seamless process.

A seamless integration !!!!

It sounds like you are buying for both so I think you have to blend the offer a bit.
