It is the online advertising agency I have been using since 2009. The first contact with them was about 6 years ago and I asked them to create a website for me. And they did it successfully.
During the years we changed my website several times. It was because of the fact that the online environment is changing and I need to be on first google page, with adequate site.
So, could say that mostly it was a hassle free process. However it takes time everything to be coordinated - content, pictures, videos. To this time for coordination and conformation could be just a little bit shorter.
