All of these sound basically ok to my ear, but Sentence3 is the best choice, especially for written communication. Indecently Incidentally, it should read: "Do you have any entry-level positions in the fields of marketing, mortgage sales or human resources?"

Also, you could drop "the fields" altogether: "Do you have any entry-level positions in marketing, mortgage sales or human resources?"
