Getting coversion rates of tour guide bookings up

I would like today to look for some feedback and suggestions on how OurExplorer can get higher conversion rates for the tour guides.
By this I mean - getting more visitors of www.ourexplorer.com to actually book a tour guide of their choice before they leave the site.

- Does the homepage of www.ourexplorer.com need to change?
- If yes, how can it change to put more focus on tour guide bookings?

Cheers
