I would highly recommend you to check any of the certified Agencies or Consultants that we have available on this link: www.hubspot.com/agencies.
Within there you can also filter the partners by :
- Industry, country, languages, services, and budget.
My best advice would be that you contact them via email and send them the list of the special tasks you would like them to complete for you and ask them if those are something they are specialed on. Even you can ask for a sample of previous jobs they have done similar to what you are looking for.
They will be more than happy to help you.
I hope this helps you to get closer to your end goal.
