Currently I'm working at a local company as a Drupal developer. Here, I've worked in a team where we developed three large projects in Drupal. I have experience with templates, custom themes, Bootstrap in Drupal 7, responsiveness, Custom/Contrib Modules, Views, Rules and other important modules that are necessary for a Drupal site to work perfectly.
The projects I've worked on have similar implementation, just like yours. It would then be easy to implement from my side, but I need more details and feed-back over time.
You can also read an article I wrote here: [login to view URL] and together with the description I wrote above make an opinion about my level of expertise.
This would be a good starting point for my freelance career. And also I speak Romanian.
Best of luck and we'll get in touch soon!
