Updates to AngularJS site

Hi Freelancers, I need an update to my site which was written in AngularJS code. My usual developer had to withdraw due to other commitments and the fact that he was in another country (USA) made things difficult - SO, I am looking for someone that will do ongoing work after this job. What I need: Overall Site: The addition of Facebook and Instagram posts with locations being automatically uploaded as pins, will require user to log in using Facebook/Instagram, please add a “Log In Via…” button to the landing page. Logging in via this method will get their name, birthday, email etc and add to our analytics. It would be fantastic if we could ‘back-date’ the pins from the last 12 months, so when the user logs in, it already has some pins on their map. The Facebook/Instagram pins will show up like a normal pin would, with the location entered and the caption from the post included and the photo from the post added to a new tab on the pin. Leave the date blank, the user can go back and edit this if required. Make the default pin colour blue (Been Here pin) as we can assume that if they’re posting a picture of the location, they would’ve been there. This feature will require the addition of photo uploads, and a photo tab in the pin menu. The current two tabs will remain plus a photo tab. They only need to be low res photos as this is still a basic site. The removal of the ‘Random City Generator’ from the LHS of the desktop site, and the second page on the mobile site (this will mean the buttons can be removed on the mobile site). The Random City Generator is confusing users at this stage, hence the removal. I think we need to remove the mountain range at the bottom of the site. It is causing too many browser issues on mobile, making it hard to use. Tutorial: Update the current tutorial based on the new site, this will require new art which I can send once the scope/new site is approved. The tutorial should be a lot more basic that the current one as we are reducing the number of ‘moving parts’. This can just be a simple click-through tutorial, exactly the same as the current. Calendar: One of the main issues users had with V1 was the usability of the calendar. This needs to be changed on all places throughout the site – some examples of new ones would be awesome! I will provide all artwork in what ever file type you require. I am also open to recommendations on the site if you have some cool things you want to do! If you need anymore information to make your bid, let me know!
