Required Website Builder Tool

I am looking for a website builder tool that can help me create an e-commerce website, Dynamic websites. My budget is less than $100, so I need someone who can work within that range. While I don't have a specific list of features, I do have some ideas in mind that I'd like to incorporate. Ideally, the website builder tool should be user-friendly and have the ability to integrate with payment gateways. Experience in e-commerce website development and knowledge of various website builder tools would be ideal for this project. If you have ready made tool also will consider.kindly let me know if anything available...
