Wordpress Migration to new Theme

详细信息

I would like someone to migrate my Wordpress site to a new theme.
The current engine is WPBakery and the new engine is Elementor.
This is the template I'd like to use.
Please advise on costs - ensuring that all links remain and that the SEO remains as is are very important.
