Tell us what has been asked of you and who is asking. We will come back with what we think it needs, what it would involve and what it would cost, and whether that is us at all. There is no charge for the first conversation and no obligation at the end of it.
What happens after you send this. It reaches a person, not a queue, and you will have a reply within one working day — with what the work would involve and what it would cost, before you commit to anything. If it does not suit us, we will say so. And because we do not remediate what we assess, we will tell you now, not after you have paid, if what you need is implementation rather than an independent view.
