I have some personal experience about offering distance consulting and, in fact, I have charged for it. According to my own experience, if you want to offer your distance advice now you have these options:
One is to hire an additional rate telephone, which has the advantage that the payment method is automatic (depending on the number of minutes the call lasted) but it has the following disadvantages:
1.- The telephone company takes a large percentage of your income, which means lower income for the professional advisor and higher expense for the consultant.
2.- It only works to answer calls in your own country.
Another option is to perform professional advice through services such as Skype. It has the advantage that counseling can be extended to everyone, but it has the following disadvantage:
1.- You have to previously agree with the person you are going to attend at what time the connection will be made.
2.- The payment of the advising has to be done before the videoconference, it is necessary to give an account number, make the payment and, if it is an international transfer, that can suppose delays of 2 or 3 days until the transfer is verified. This of course is not operative when the advice is done through the Internet precisely because of the urgency of obtaining the response from an expert.
Considering the problems that I have encountered in online counseling, I think Experty.io can offer some solution to these problems. Experty.io is built on the blockchain that, by itself, is specially indicated for micropayments, eliminates intermediaries and makes payments secure and fast.
In addition, Experty.io solves the problem of automated payment by minutes to which applications such as Skype do not solve.
And an other advantage: highly qualified professionals from countries where salaries are very low may offer their services to other parts of the world where salaries are higher, which will be a good opportunity for these professionals.
