My titles in USA

Presently I am in Nigeria, heading for Canada (as soon as God permit) but my books are published in USA by Wordclay Publishers (www.wordclay.com), however, I could not promote the sales of these books as I would have love to - please advise me on how , despite the present distance. The titles are:

The spirit of Nimrod, Prosperity in Christianity, Mercy:the chief among others, Beyond the torn veil.

Thanks for your love and concern
