Guiding others to feasibility studies on the internet in return for money
Question

                I find advertisements on the internet like “I have 100 million and looking for projects’ ideas” then he receives many responses on his website. It seems he needs many feasibility studies. I have replied and told him that I can guide him to see many feasibility studies which are available for every one on the net. He said to me “if they are really many I will give you 3 million” is this deal Islamically permitted?.
Praise be to Allah.
    There is nothing wrong with guiding others to permissible 
    commercial ventures and feasibility studies that are connected to them and 
    there is nothing wrong with receiving payment for that. This comes under the 
    heading of fees for brokers and guides, which the fuqaha’ said are 
    permissible. 

    Shaykh Ibn Baaz (may Allaah have mercy on him) was asked 
    about the ruling on looking for a store or apartment for a renter in return 
    for payment to be paid by the one for whom he finds what he wants. 

    He replied: There is nothing wrong with that; it is a kind of 
    wages. But you have to strive hard to find a suitable place that the person 
    wants to rent. If you help him in that and look for a suitable place for 
    him, and you help him to reach an agreement about the rent with the 
    landlord, there is nothing wrong with that in sha Allaah, so long as there 
    is no treachery or deceit; rather it is done in an honest and trustworthy 
    manner. If you are sincere and fulfil the trust in looking for what is 
    wanted, without cheating or wronging him or the property owner, then you are 
    doing something good in sha Allaah. 

    End quote from Fataawa al-Shaykh Ibn Baaz (19/358).

    You should beware of scams that are operated via the 
    internet. Someone may take part who claims to have money and to be prepared 
    to pay the fees, so that people will get in touch with him and thus he will 
    get a percentage of the cost of phone calls, and other kinds of tricks and 
    deceit. 

    And Allaah knows best.
