From how you described your flat, I'm assuming that there are other owner occupied flats in your building. I don't think that the moisture is limited to your flat.
1) I'd get the other residents involved.
2) Mold is serious, but probably not a panic situation. Take the time to find a reliable firm to evaluate your problem. I know that is difficult. In the US, I'd go to my local health or building department for advice. We also have independent building inspectors that will inspect a property before we purchase it. Expect to pay for advice.
3) Some people will try to take advantage of you and some will not. Recommendations from friends are a good way to find someone.
