Bugfixing on Drupal Site with OpenLayers Module

I need someone who can help me with a Drupal Site. Some Years ago a developer helped me to design a drupal theme with custom made sites. Because of lack of time I didnt finish the project at that time. Yesterday I started to restore my backups. So the Website is now online and accessible. Most parts are working fine but I have several problems with the Modul "Open Layers"and Google Maps (using Open Layers). Therefore I need someone who can remove the bugs in the site. At the moment Drupal 7.53 with Open Layers 2.13 is installed. There is no real content at the moment, its a site in development. I made 2 screencaptures. When I click on "Adresse auf Karte anzeigen" (Show adress on map) it doesnt display the map with the actual OpenLayer Settings. I also tried to make changes in OpenLayer but actually i couldnt find a workaround. In Open Layers the maps doesnt show up in Preview Mode (Failure for google maps etc.). OpenLayers should be updated to the newer version 3 and the site should get the necessary updates at the right points. Also the Sharethis Buttons should get a CSS bugfixing. In the second picture you see the overview "Views" Site. There is somekind of break. I think this happend when importing the MySQL Backup. There are Linebreakers in the database that should be elimiminated, so the View works fine again (had a unseralize error after the migration that I fixed but still the display isnt right). As I didnt reach the developer from last time I need someone else who can fix that fast and reliable.
