Patricia,
I can't tell from what you say whether you'd find what you're looking for at Wikitree. Wikitree does not conduct DNA testing -- and its emphasis is on creating a large, accurate, shared, global tree that eventually (in an ideal world) connects all of us together. We do allow DNA tests to be added to your profile here -- but the usefulness of that DNA is very dependent on the paper trail that exists (or can be built) here.
The people on Wikitree are volunteers. Wikitree is free. This isn't a big commercial company that you pay and expect to have them "do something" in exchange for money. Instead, it's a community of mostly very helpful people -- some are professional genealogists, and many are amateurs seeking to learn more about their own backgrounds.
We do have people who have volunteered to be mentors to newcomers -- but again, we are all volunteers. You will be, too, if you decide to join Wikitree. And if you do, maybe someday you'll be taking someone else by the hand and helping them learn about, add to, and improve our shared tree.
Here's a link to an introduction to Wikitree, in case I've misstated something.

There is a learning curve, and it can be frustrating, but for the most part, people are happy to help.
If you're interested in learning more, ask more questions here in the forum. Maybe someone else can explain Wikitree better than I can.
I see that Stephen has responded more quickly than I, (and did a better job of answering you), but I'll go ahead and post this anyway.
