I am working as self-employed software developer and trainer doing technical consulting, see bio below. I typically deal with large companies such as Siemens, BMW or Telstra. Also I work on behalf of software companies such as Oracle.
I wrote a book about Cloud Computing which is almost finished and needs a cover design (front & back, one file ).
The book will be printed by the largest UK POD company so some rules have to be followed regarding file format, size etc. (see below)
-- I am happy to put the designer name and web site in the book cover so it might be good advertisement for you as well --
Please use one of the templates. Also please mention which file format you can provide.
