I need stock exchange website

I am looking for someone to build a trading platform for my stock exchange website. The primary function of the website is to provide users with a platform to buy and sell stocks. I require basic buy/sell orders to be available to users. Additionally, I need additional security measures such as SSL and encryption to be implemented to ensure user authentication and data security. Ideal skills and experience for the job include proficiency in web development, particularly in trading platform development, as well as knowledge of security measures in web development.
