    “He do a good work, where there is no need to edit much on his work again after him. He know well what he do and delivered the work in the best shape it should be. Give things that I didn't ask for as reference even it is part of work another freelancer forget to give it. his work very tidy and professional. I try to give him more days but he give me in few hours. He don't delay the work if it is not need and no reason. More over when there is some points not clear for me he explain it in a very good and clear way. He make the file in every good form from every small details to the biggest one from size to space, title and number the tables and figures. He simply make you happy from the first moment you look at his work he know his job and he do it honestly and with a lot of love and respect. Even he give me what I forget to ask him before start the work and not refuse at all. The budget meet the time and work he do. He delivered a perfect academic writing and statistical work. Glad to know and hire him.”

    “Gary was always polite and his knowledge of stats seems pretty good (though some details were missed). We had a terrible time communicating, perhaps it is just our styles. First deadline was missed, but he was helpful when we worked together online so I committed to another deadline with him and confirmed several times with him that it was clear and that he would let me know if he couldn't meet it. We had some hiccups to the stats in the meantime, so I allowed for that, and after a few days past the second deadline, followed up with him again. He constantly reassured me not to worry, but mind you this is for a project that said "urgent help needed in the next day or two" in the title, and I reminded him more than a few times that the deadline was pressing. He was ultimately quite unconcerned about the deadline, so I had to cancel the project in the end and find other means to complete the task myself. Perhaps he would be fine on a project that had no particular deadline, but unfortunately his work style is completely incompatible with mine.”

    “He did a perfect work for me but instead of delivery in one week he took 3 weeks. So, if you are looking for perfect work regardless to the time he is the best choice.”
