If I wanted to go with choice #1 what would be the most effective way of convincing a bank that I have a solid project?

As a single member LLC your choices are corporation or disregarded entity.  

To determine if a particular location will be a good choice, I use Trulia's crime map, Google street view, and input my my RE agent/broker/property manager, @Rachel De Faut.

An overall thickness of 4mm would be my choice with a minimum of a 12 mil wearlayer combined with some type of scratch resistant coating like AO or ceramic bead.

It's your choice if you want to be a service business by lining up the money for borrowers and lenders, collecting the points and shedding the risk or by being the bank by lending your own and other peoples money and holding onto the risk.

This limits your choice of lenders and the LTV they will lend, but it is still an ability to leverage the IRA dollars.A non-recourse loan may be used for the initial purchase of a property, done as a re-fi or even applied as a portfolio loan to several properties held by your IRA.The use of debt-financing creates exposure to a tax known as UDFI.  

Though, i  conjured 2 choices on how I should proceed with this...  

Her other clients are where I aspire to be and my choice to hire her was because of that.I would advise you to ask more seasoned investors in your area who they work with.  

Once I find a financial company that allows investing in real estate, should I specify that the new account should be a Roth IRA or is there a choice? 

You still have time and from the looks of it the property also is a good choice.
