We are a London-based ecommerce design, SEO, link building and traffic management firm and also develop content for several retailers who have high traffic rankings. (One of our clothing clients currently has No. 1 google and msn rankings, a No. 5 ranking in yahoo and has a top 10 Alexa traffic rank for sites in its category).
Although your budget is small, we would like to work with you and can offer a very fast turn-around time for the project of between 3 and 5 days. See examples of our ecommerce design/redesign work.
