As a wholesaler, I am a self-represented investor, and as long as I disclose in my cover letter to the seller that I am a licensed agent, self-representing, that I have a financial interest in the transaction, and that I am not representing anyone else in the transaction, I can do wholesale contracts.  

Research how brokerages function and what a sales person's role and financial responsibilities are. 

Is there any chance to receive a financial backing to move ahead with this project? 

I'm sure most of them started with the same idea as you: work part-time until they are more financially stable and then jump in full-time.

Banks/credit unions/“portfolio lenders” will usually require loan applications, financial history docs, other various paperwork before being approved and most take a bit longer to close.

(House-hack)The main reason I'm getting into real estate is not only financial freedom for myself but to get my parents retired.

Make sure there is financial incentive for the contractor to complete the job and get the last draw.

I work in the financial markets and have always had a passion for real estate. 

My ultimate goal is to have side income through rental properties and to eventually reach financial independence.

But as reality sets in, I probably can't swing both financially at the same time.
