Federal defenders are excellent attorneys. They work very hard and have excellent qualifications. Guaranteed a federal defender will work very hard on your case. But, at the same time, if you can afford to hire a private attorney you should do so. If you hire a private attorney you will get to choose who represents you and make sure that person fits the style of representation you desire. If you use a federal defender, the system will choose the attorney.
I am sorry you were injured. It is especially difficult when you are self employed and probably don't have any disability insurance.
Slip and fall cases are actually pretty complicated. Give a call to a Pennsylvania lawyer who handles slip and fall claims. S/he will discuss your case with you at no charge and advise you whether a suit is appropriate.
If you have a successful claim, you would be able to recover for medical bills, lost wages and pain and suffering. But that is a big if.
If you have full tort insurance a lawyer may be able to help you recover some compensation for the pain and inconvenience you experienced. If you have limited tort, if your injuries are not serious enough, you will not be able to recover for your pain and suffering, so there is no point in hiring an attorney. In the end, it doesn't hurt to speak to an attorney. It won't cost you anything and you will be able to get a sense of your options.
It depends on who is judged to be responsible. If you are judged to be responsible and she is injured, yes, you will probably be sued. But that is why you have insurance. The insurance company will handle it.
Oh my goodness this is a bad idea. I am glad you are wise enough to ask the question. As my colleagues have stated, you want to be the one to control access to your pool, not someone else. After all, you are the one who is liable if something happens to someone.
