I need an "About me" write up for real estate

I'm a new realtor in Houston, Texas (less than a year). I need an "About me" to post on my webpage/facebook/instagram. I have over 20 years in sales experience and 15 plus years in managing teams of sales for different companies. I currently sell properties in an art district and I also sell vacant land for commercial use in rural areas. The key to my success is my network of people and expertise in understanding the housing market. My broker is an expert in real estate and has over 40 plus years.

I would like it to highlight me as a competent professional with integrity, who will get the job done. I sell homes to land for commercial use. I have a clear understanding of the real estate market. It should be concise and straight forward. Max of 250 if possible.

How long would it take for this kind of write up?

Thanks!
