I own multiple business using a series LLC for my real eatate business, an LLC field as an S Corp from another business and I have one from a prior business just as a regular LLC (I really should close this one but it costs nothing in our state to keep it open other than the time filing the annual paperwork).

My banker knows the guys and knows that he has received numerous offers over the last few years to buy the building.

Sounds like you're well on your way to success in the field. 

There are numerous foreigners, but they all seem to be from China, Hong Kong and Thailand.  

I am outgoing, outspoken and confident in my abilities to go into this field, please help. 

What wasn't mentioned is there are several cities in the state like San Marcos which requires a general contractor to pass the national ICC's contractor exam which can be taken at numerous testing facilities and is similar to the licensing requirement in a lot of other states.

I have been working in the science field, specifically pharmaceutical, since I graduated in 2013.

(Numerous exceptions exist, this is just general rule).

I am looking to get started in this field in San Diego.
