    “The worst thing with a freelancer is when he silently abandon a project. Even unskilled novice is better than sudden disappearance. This is what openchallenge did. A lot of time invested and lost with zero income. Moreover - with negative income due to necessity to search another freelancer and explain the same things again.”

    “I actually rate OpenChallenge a "20". Not only did they deliver within budget and ahead of schedule, but they did work above and beyond my expectations. Umar made himself available at all hours, and was not satisfied until I was 100% happy with all the work. I am very thankful that I found this team and am looking forward to working with them in the future. This team is very knowledgeable in WordPress and website design and graphics, and I HIGHLY recommend them. I am already in process of our next project with them. Thanks OpenChallenge!!! Jim”
