Wordpress Site Update

We have a Wordpress website redesign that we want some help implementing. We've created a new theme (using an AI converter from Lovable to Wordpress) but aren't confident in our web skills and want someone experienced to help us update our website to match the design. The design is done, we're clear on what it should look like and how it should function, but we need someone to execute. We use WPEngine and have a dev site in place where we've been working.
