Answer:
The ThemeCatcher support team will help you get React customized and up and running, as long as it is in line with the existing technology available with the theme. We can also advise you on any topic related to the theme.
However when it comes to adding third party code (not included in the original package) or custom code, you will need to employ a developer or execute the work yourself. Whoever is taking on your customizations is free to contact us for help on integration process, conflicts or bugs.
