    “Very good freelancer. My only issue was that they had not read the brief of what I was looking for properly before bidding. I wanted to provide a spreadsheet of information and for the freelancer to convert this into a visual report, something I wasnt sure whow to do. After guiding them the freelancer provided what I asked for, although in the end I started to learn the task myself and in the end did not use the freelancers work but used my own. All in all I could have saved myself the cost if I had put the effort in myself initially, The reason I posted the project on Freelancer was the fact that I did not have the time to do it, I ended up having to spend that time.”
