The LLM consensus is option a). This has been discussed before though. Whether that discussion has been laid dead now, I'm not sure.

But on to the Job Centre. I'm not sure how well it works now, but in the past at least, it was said it was okay to hire staff if the Job Centre did not do it for you after a reasonable amount of time.
There must be issues with it because there are always plenty of staff interested, though often none apply to adverts after months. So I would actually say, if you haven't had any apply after a month or two, it's okay to get one the other way. This is naturally much easier if you have an assistant as you can filter out the uninterested ones.
