Premiumpress

Hi, I have a property website [login to view URL] and is operated on Wordpress under a premiumpress theme. There are a number of tasks that need completing. 1. The website has a front page and in the nav menu there are a number of options rentals maintenance, international, in these options for eg international there will be a list of countries Bulgaria cape verde etc, once that you click into these areas what I need is the option to create a new nav menu with new pages that can be selected. If possible if this could be done in a widget so I can add this to further pages in the future. 2. Once going into these pages I also need a new home page created or a template created so I can create further countries in different areas. 3. I have started on A website search box but if possible if this could be customised on the main home page for sales and rentals in the same box. I am not sure whether the categories in the search box may need linking up to the fields when filling the criteria for each property so all working correctly. There may already be plugins available, just haven't had a chance to look through them, will look forward to working with you,mthank you.
