Is there a CRM for these requirements?

Question

CRM

The contractor went through 15 pieces of CRM, as a result we are sitting on Bitrix. But you have to block ads and endure some interface features. I understand that free products involve some inconvenience, but still there is a lot of CRM, it is possible that I missed a good one.
I'm looking for this one:

• Free for 10 people
  
• Time tracking for each task
  
• Structure: projects, tasks and subtasks
  
• Access restriction for freelancers
  
• Checkboxes
  
• Email alerts
  
• Russian language or the ability to make localization
  

Maybe you know something that will fit these requirements?
