Develop my website

Hello, I need to develop my existing B2B (wordpress) website. The company has been created in 2012, based in France and provide engineering and industrial purchasing services to the OEMs by optimizing the economic performance of future serial products (automotive, energies, agricultural machines, railway...). Currently, I am sub-contractor of other consulting companies but I want to address the final customers directly, with a good reference such a professional web site. So the aim of the project is to attract new customers, make the site more engaging and good looking. I need to create basic graphical identity(logo and theme serving also to the corporate presentation, incorporate existing images illustrating executed projects). The target audience may include executives from different fields - purchasing directors, design to cost managers or finance/product controlling. The site is bilingual, French and English. I will provide further information to the selected candidate, The criteria will be existing portfolio and solid references, With best regards, Maxim
