@Presh DineshkumarMost of the Plus and Pro membership "perks" are very U.S.A. focussed - even the on-line calculators - and have less practical value to Canadians ... even those unfortunate enough to be stuck in the GTA ;-)Some Plus/Pro features .. such as the search members by zip or postal code now work (sort of) for Canadians (polite nagging can pay off ).If you are a flipper, or offer a real estate related service (architect, trade, etc), then the ability to post advertisements to the Real Estate Marketplace is a benefit.I upgraded to a Pro membership early on to support the site and its growth as I found it to be a credible venue for exchanging knowledge and making contacts with respect to real estate. 

I would now like to seek some professional guidance from an architect, residential construction contractor, etc. to first gauge whether or not my vision is possible, potential road-blocks, and alternative development ideas.

There are rules you will need to follow and you may need to work with an architect as well to walk through your vision.

Recently married an architect and we'd like to explore more seriously leveraging her skills for a potential real estate business investment.  

Interior designers and architects then pick out colors from there. 

Im looking for referrals for architects in Los Angeles.

Pay all the soft costs (about 20k more for total architect/zoning attorney/surveyor and acquire the plans and sell the lot from there?

I'd like to create a series LLC with my wife, who's an architect.  

My wife is an architect and we have private investment capital available, but we don't have that much experience in the CA market so we'd like to meet people involved in new construction (passive house), add value projects, as well as re-entitlement and fix and flips.  

Another $1k for architect (a friend of ours who really did us a serious solid) and permits.
