I read and understand your project
Hello.
I am selling my only PTC site that is Established and running from over two years. It's based on script with lifetime paid license. Moreover, It's open source so you can edit and develop anything you want. The site also has an attractive design and everything that is needed for a great start. You won't need to search for every single thing individually since it contains everything you need.
If you are interested, Please feel free to Contact me to discuss further.
Thank You.
