You're wrong on two accounts: It isn't a favour, "i will pay in csgo skins." That is a transaction, which is completely fine and legitimate if both parties are fine with it. Also I am responding to the other poster as you are to me. In which case, if I am off-topic, then you are also. In any case, the poster was simply highlighting the value of such an expert for such a job, which they are entitled to do as it is exploring the OP topic and makes it a broader discussion.
