Hello Friend,
I am an expert Opencart developer, I can do this job with perfection. I have some questions please respond:-
1. Do you need exactly the same design?
2. How many extensions do you have?
3. Any customization done on existing opencart store?
4. There is little confusion in project description which can be clear on personal chat, plz send message so we can clear specifications.
Or Do you need only data to the latest version?
You can check my reviews for my experience.
Thanks,
Pankaj
