Complete transition from Vantage to Javo theme on Wordpress

General information for the website: Online directory
Description of requirements/features: A theme change on the website thehenplanner.com from Vantage to Javo

Part of the work has been completed by another developer who has disappeared mid job.

The key items are:

1. Ensuring the search function works (it might need a workaround and interaction with the theme authors)
2. Styling / layout of menu, header, homepage, search / directory pages, blog and other pages
3. Ensuring all the blog and pages links remain in tact when the transition happens for SEO purposes

I haven't put a budget on this as I want only experienced developers to apply who are familiar with themes like Javo

Current website thehenplanner.com
Test website (work semi completed) http://www.marquismartin.co.uk/newtest/
The theme is this: http://themeforest.net/item/javo-directory-wordpress-theme/full_screen_preview/8390513
