Dress up if u want to be taken seriously.

When my wife had a bridal shop, she was approached to be in a show.  

I was sure to dress in suits and no trendy hair or piercings.

Learn the real estate lingo and sound and dress professionally.It is important you choose a niche and focus on brokers who deal with this niche.  

What that is is more of a listing agreement dressed up like an option, it's pure horesfeathers.So, I can see any state regulator considering that "option" as a disguised listing and brokering if that optionee is not a licensee and even if they had a license, there would likely be other issues, such as a net listing and brokering requirements.

Dont overthink the website, cards, etc...you want people to take you serious so you need to show you are serious so I think some signage on your vehicle, some business cards and a basic website and dressing for success is a great start.Give cards to everyone  you meet and tell them you are a RE investor...go to every REI meeting you can and start shaking hands and asking investors what kind of properties they are looking for.Differentiate  yourself...don't be lazy.  

Here's a few: dress appropriately, have good hygiene, if you have biz cards make them look professional, buy a domain name for your email address, create a website, make sure your online profiles are up to date and professional, have a professional voicemail message, return phone calls and emails, don't give someone a dead fish handshake (own it), listen, take care when writing emails, and the list goes on.

Dress up as a coc...
