Promote a facebook page for an upcoming science book

Next weekend we will launch a Facebook page for a non-fiction book, which will be published in June by a major publisher. May is a bad month because everyone is on vacation but we would like to ensure that the page gets a large following quickly. Especially in the areas of science and technology and primarily in the US, Western Europe, Japan and China. We are looking for an expert, who will use credible ways to increase the fan base of the page and initiate the first phase of promotion. If we like the work, we will offer an extension of the project and several similar projects.
