I need a Drupal Developer for DGPR changes and other fixes in my site

I need to get a DGPR drupal module installed, to Enable Cookie policy, Allow users to cancel their own user account, Users need to be able to request for removal of all their personal data. I want to have a new technical connection in eCommerce (I use Paymil and want to replace with Alpha Bank eCommerce) I need some changes in my shipping methods: I offer slow and quick shipping and now I want to give customers one more option of ''traceable shipping''. I generally need a Developer whom I can possibly pay a subscription to and contact them whenever an issue comes up or I need changes in my site.
