The prominent venture capitalist, Paul Graham, wrote an great essay on the topic of startups doing things that don't scale - http://paulgraham.com/ds.html

You’d need a good architect to get this through SF’s arcane planning and bldg depts, but it can be done.

You need an architect and a team of engineers for something like that.

They will most likely want some form of the following docs:- Existing Building Plans that are drawn and stamped by a licensed architect- A full survey- Condo Docs that are written by an attorney- Some sort of notification that is sent to the tenants and neighbors informing them that you intend to do a condo conversionHope that helps!

You can also look up local house designers and architects, last would be Internet sites.

Can you please recommend good landscapers or architect/interior designers in Austin/Houston/San Antonio/Dallas (central Texas area)?

Specific things like;- Did you hire an architect and develop the plans or out the gate used your GC's architect?

That being said, I knew what FAR I wanted to hit so even though I had restrictions, I worked with my architect to get and exceed the FAR that I wanted. 

Measure how much money you spent, take lots of pictures, or a video if you really want to impress and send out an email to your investors (bcc everyone who will benefit from the info, the builder, the broker, the architect, your partners, the bank) every week like clockwork.That is the important part.

All of our managers are certified in their particular field (office, apartments) We too benefit from having a construction group as well as an architect.
