They were happily married and were indeed tentmaker (Christian missionary) ministers for God's glory.
The Apostle Paul did that practical, much-needed work as well. Why? Well, he did not want to become a burden to anyone, yes, and not wanting to charge a fee when ministering the gospel message. False teachers are into that lame method.
Jesus the prime example (Savior, Lord) for us all was a man's man and really worked diligently as well (perhaps not with carpentry or with tents. In the Bible we never see Jesus doing carpentry work. He probably did help his dad how when young. I don't know for sure, but Christ is my mansion-builder now. Been working on mansions).
If Aquila and Priscilla had not known Christ before meeting Paul, they certainly met Jesus after encountering Paul, for no one could spend time in Paul’s presence and not be infected by his contagious and enthusiastic love for his Savior. These two who lived together, worked together, and suffered exile together, came to know and love Jesus Christ together, and it made their marriage complete.
They were together in this. In fact, they were always together. One’s name never occurs without the other. For one thing, they made their living together.
“For by trade they were tent-makers” (Acts 18:3).
Every Jewish boy in New Testament times was taught some kind of trade. Since tents were such a prominent part of Hebrew life, Aquila’s parents chose to have their son learn this practical means of earning his livelihood. Their tents were made of rough goat’s hair fabric which took great skill to cut and sew properly. Aquila had acquired that skill and later taught it to his wife, and she happily assisted him in his business.
Not every husband and wife can work together like this. It takes a mature relationship to work closely under the kind of pressure a job sometimes generates. But that is evidently the kind of relationship Aquila and Priscilla had. They were not only mates and lovers, they must have been good friends and companions. They had to be willing to give to each other more than they tried to take. They had to be able to accept suggestions as readily as they offered them. They enjoyed being together and working together. They were inseparable, and they were equals (read more on this couple with the right priorities).
