Combine jira products

[Dimitris Chatzimichailidis]

Hello guys. 

Our company is a Real Estate Company which needs to contact and support existing and possible clients and also manage developers tasks for these clients. 

How we can combine Jira products to achieve these functionalities I described before?

I want the tasks for a developer to be connected with a client's feedback or support request. Is this possible?

From your description, I'm not sure you need to combine anything.

Plain JIRA can record issues created by clients (and developers).  The developers can work on stuff, and make comments to ask clients questions, and the clients can feedback on them too. 

So you can do it without any fuss.

However, I'd recommend a look at JIRA Service Desk - this simplifies the interface for the client, and means you don't have to expose your entire JIRA project suite to any client who might need to feedback, or let different clients see the requests from other clients.
