Logo to promote free community gym

Hi, I am a recently retired military member who has recognized a problem in my community. Too many people spend too much time alone with nobody to talk to, and many of my neighbours simply do not move enough. I am lucky enough to have free time and energy as well as the skills to help address these problems. I am looking to start the free gym on 5 September (Labor Day) and will then be offering the free fitness class every evening in the local park. I want to encourage as many people as possible to join in and to do so i want to have a logo created that will allow me to promote this initiative on social media, and using posters and small cards that will be handed out around the neighbourhood. This free community gym will always remain free, and will be designed for all ages and fitness levels. I just want to bring my neighbours together in a positive way. I am a big fan of Star Trek and would like to use the live long and prosper symbol to help promote this initiative. In particular, I am looking to use this symbol with a golden circle around it. Because I dont have a lot of time before 5 September, I would really like to get this project completed sometime before 19 Aug, if at all possible. Although I am planning to offer this service to my community for free, I do believe in this initiative enough to put my own money to get the logo made. That said, I have no idea how much something like this costs. Any help would be greatly apprecieted. Many thanks, Matt
