Well, Grace . . . welcome to Christian Forums; God bless you about this, how He is able to bless and so satisfy you
The first thing I think of is I would hope you would have a partner to help you with bringing up your adopted child. And it would be good for the partner and you to be an example to the child, of how to relate in love. So, I think it would be needed to have a partner.
And a man could be good, since then your child could have your example of how to relate in marriage
So-o-o, Grace

You can see how my logic kind of leads to marriage, for you.
But I suppose you could adopt someone who is older and disciple the person. But it might be right to have a female if you are going to live single with an older child. You might find out who is a faithful and proven young adult. And the person would come of age, in not too much time, and then you might be adult partners in some ministry.
Best of all, pray. Trust God, how our Heavenly Father is able and has such a perfect plan for you, with very good surprises of so more and better than whatever we can think, now. But details could be the same, how maybe He could give you a child but how it works could be so better than we could think and expect, now.
I think if you were ministering with a missionary group with orphans, for example, then you could partner with others in the missionary ministry, so you could bring up the child together.
Also, it is very important to have mature and seasoned seniors who lead by example, so they can feed you their example while you all labor with one another. And your child, if you did adopt, could have senior mature Christians as well has having you so caring for your child.
Or, labor with an orphans ministry, and have all of them, not picking any one out

But in case you have your own adopted child, she can be with you at home if that is away from the orphans, and she can go with you to help with the orphans. It could be good to have someone who has lived with you and has been brought up by you so she can help to spread this to the orphans or other children being attended to by a ministry.
In any case, I would say you care, and so God has a very special creative plan for you . . . along with your other Jesus family people with whom He will have you sharing > it will not be you by yourself. And now you have us and we have you, also
