First of all, this guy knows Maths. If you have anything Mathematics He is your guy. Secondly, I really appreciate his conduct; he actually made sure that he could do the project even before contacting me, he gave me a fair price first time (No weird negotiation tactics), and he delivered when he said he would. I wish you great things bro. This is the type of guy who is actually out to deliver value; if you treat him fairly and respectfully, he will treat you the same.
