Hi
I am an expert in Masterstudy 3.0 theme. I have worked on this theme in different websites. I know all the ins and outs of the theme i.e. from where the specific data is coming. I can do all the work that you have mentioned i.e. Design Customization, Responsive Design, Content Upload, Plugins/Extensions, and E-Commerce Functionality. The websites that I have developed in the same theme is [login to view URL] and other beings of someone else whose URL I cannot share due to security issues.
I am highly qualified for this project and would love to speak with you further about this project. I can start working right now. Client Satisfaction is My Motto. Looking forward to hearing from you soon.
Best Regards
Divdeep Singh
