Fix Opencart site Juornal template -- 2

I need to make some changes to my site. The changes are design and code. The changes must be made from the management panel of the template in Opencart. 1. Update the template to the latest version in use. I provide the original template purchased on Themeforest 2. Fix a bug in the Catalogue > Manufacturers [login to view URL] 3. Check all buds on the site 4. Insert a Tracking control and management module that customers can consult via login. We can also purchase it. 5. Configure Stripe payment module 6. Make sure that the site works perfectly on all mobile devices 7. Solve all attached fixes I'm looking for an Opencart expert. I will pay after the completion of the work so do not ask for payment first. The budget for this project is $60
