Hi,
Thanks for posting this work specification.
Whilst I have many years of experience, this is the first time I have used Freelancer to find work.
What you ask is second nature to me, there are no learning curves for me and I will do everything I can to exceed your expectations.
Please check my portfolio, I'm very thorough and like to play an active part in the development and refinement of new functionalities on the web.
I hope to hear favourably from you.
All the best,
Nick
