Thanks for explaining more.
As an analogy, consider a new parent who felt all at sea with their baby. It seems to me that where you are coming from - with your tutoring expertise set off against your relative inexperience in home ed matters - would be like that of a professional who had worked in a nursery and knew how babies are looked after in such a setting. It might appear that looking after babies in a nursery is similar to being a parent, but it really is a completely different enterprise. If anything, their advice would be more likely to be undermining and unhelpful, the more so if they were very confident of having the answers. I don't think you've been sufficiently immersed in the world of home education to appreciate just how different it is.
The message which long-time home educators give to newcomers is not, "here's how to assess your child to see how they would measure up in the system you've just left" or "here are some professional tips to help you in case you aren't up to the job". Rather, we go to great lengths to assure parents that "your child is unique and isn't ahead or behind: education is a journey, not a race". And "it's fine, you can do this, trust your instincts, you know your child better than anyone." And "there's no hurry, you needn't rush into spending money, you'll find your way in time". Those who feel all at sea are encouraged not to seek professional advice straightaway on what to teach for things like literacy skills and maths, but first at their own child, to watch and wait and gain an understanding of how that child learns and what makes them happy.
In fact, unless the parent or child has a strong desire to do otherwise, the usual advice is to start off with a period of "deschooling" during which there is no enforced formal learning at all, to allow the child to relax and settle in while giving the parent time to see how the child responds when she has the time and space to learn spontaneously.
The reason some of us react fairly strongly against non-HE folks offering advice to new home educators is because we have seen so many teachers and tutors who have a little knowledge of home education but who don't really "get it" offering their services to us. They are sure there's a demand for what they do, but they may well be driving that demand themselves. It seems to me that nearly always this is done in all innocence, but still it causes problems. (The same is the case with some Local Authorities' self-styled home education advisors, who may indicate that families should follow school-type lessons and timetables. I'm sure they believe what they say, but they don't know about home education and their advice may do more harm than good.)
There is a lot of expertise in the home ed community, which is freely given. Where parents can't access it locally due to personal circumstances or living very rurally, many forums are available.
Maybe some of the things you are proposing to offer could be helpful. But those aren't the things which will make you any money.
