Our fast and hard reply is no. We usually do not jump halfway through another project in order to finish it off, or do not update and add to a maintenance package websites we have not developed. This is not because we are picky. For the most part, it is because your original digital marketing agency probably has a different approach and tools than we do. We are here to help, however, so we can gladly discuss how we can make a complex situation like this to work.
