Need theme installation COVENANT

I need Covenannt theme installed on www.AskGodFirst.com and all the files that come with the theme.

Everything is simple and God bless!

I have $20.00 for everything!

Please install theme in 24 hours maximum.

Theme details: https://themeforest.net/item/covenant-timeless-wordpress-theme-for-churches/60457517

When I tried to install it it gave me these messages:

Categories and Tags Converter
If you want to convert your categories to tags (or vice versa), use the Categories and Tags Converter available from the Import screen.

I just want a professional install it and all the files so I won't have issues with the website.

Thank you!
