Completing unfinished flight & hotel API integration -- 3

I have a template which is made of yii2 code in de backend and the frontend is angularjs. I hired about 3 months ago a developer to integrate for me the flight and the hotels API as required from travelpayouts. The developer did some work and there are some issues that I want to fix them and also continue with the rest which is remained after I stopped with the developer. The URL of the template is hosted on my dedicated server [login to view URL] What I am looking for is the following requirements 1- Create a hotel page please check the link below [login to view URL] and implement API using the code from the guide reference below [login to view URL] You can get photos and other information about the hotel with the help of Hotel Data API [login to view URL] it has to be the same or a similar of the design and the functions for the results and the details and it uses my token and marker id. 2- 11- create a page for Price Map API [login to view URL] it should look like this [login to view URL] 3- Add more currencies 4- add more languages translation menu to the site no 3 and 4 must be the same as [login to view URL] please check it on the site 5- create About us page and store my text in it. 6- Privacy Policy page and store my text in it. 7- Activate Facebook and twitter icons on the index 8- The share buttons of twitter and Facebook need to be configured in the flight search results to let the users share there results with others via there accounts Here is a link that explains how you can do it with Facebook [login to view URL] 9- Create WhatsApp Share Button also in the search results Here is a link that explains how you can do it [login to view URL] 10- the price sorting in the flight results is not working as it should because it shows not the cheapest price always on the top of the search 11- the favorites button which is created on the search results should save the results for the anonymous users there is already created a database for that with some tables 12- I do have an index page with a good design I want to use it as the frontend [login to view URL] All the work will be on the server because the token and the marker are working only from the server host since it's tied to the IP and hostname, so there will be only valid requests from the server not from outside. You must have good knowledge of YII, AngularJS, PHP, MYSQL, API integration, Javascript, JSON, MAX bid is $500
