"The end result of this project exceeded my expectations. The expertise of the contractor is of the highest standard. The contractor went out of his way to present various alternatives to the layout/design of my website some of which were accepted with gratitude. But in the end the only thing that matters is what the client wants and to that end we got exactly what we wanted, a site expertly designed to perfection for our requirements. The contractor was available at most times to assist and communication as well as the ability to resolve queries was always at best. I unequivocally recommend this contractor to anyone in need of assistance or development of WordPress and/or WooThemes."
