Do startups need advice on business organization?

Now, like mushrooms after rain, all kinds of websites, communities, services and social networks appear, develop, sell and re-create. In a word - startups.

Facing on duty with similar undertakings, I notice that very often smart, advanced programmers are far from doing business as such. After all, in order to create a successful startup, it is not enough to know PHP or, say, Javascript. After the first stage - writing the code, a lot of organizational issues appear - from legal to personnel. And on these "managerial troubles," many stumble. It is understandable - if you are good at programming, it most often means that you are far from other areas of knowledge.
In this regard, the question arises.

What do you think, will there be a demand for such a service as Business Consulting ?
I will explain what it is. We have the opportunity to organize consultations on the business remotely - via messenger, by phone or by e-mail. There is an opportunity to organize your site. There are experts who are ready to provide these services. As far as I can imagine, this can be very useful for many people. After all, it is not necessary to create another workplace, to keep a person, it is enough just to write / call and they will help you.
