I strongly, strongly advise against letting other people have access to your PC, especially strangers. It doesn't matter how nice they seem, or even if they were a community moderator, it's still very risky. It's also against our guidelines to offer monetary payments.
I recommend you watch some tutorials and try modding yourself. If you need help, please create a topic and ask. Doing it yourself is a lot better than having someone else do it, and a situation arises where something no longer works, and you come to us asking for help. At that point, we can't offer help if you have no idea what exactly was done to your directory.
