Need someone who's expert in https://www.bigcommerce.com/. need help with integration

I am looking for an expert who is knowledgeable and experienced in https://www.bigcommerce.com/. I initially need help with integration and have an account with BigCommerce already set-up and ready to go. I'm not sure of a timeline so I'm hoping to find someone who's flexible and open to discussion to complete the project. Although integration is my main concern right now, I would appreciate it if the person could assist me with customization in the future, too. Any help is greatly appreciated!
