Hello,
I am Rajesh, an experienced web application developer. I also run a small development service which you can find at: www dot eazium dot com. You may find the numerous websites built over the recent months in my freelancer profile(Although all haven't been updated to the profile yet).
I had missed the PPT previously. Seems like you have already created UI layouts. However, to be honest, I think the database structure has to be much more complex when running a payment processing ecommerce websites. I hop I can be of any help in this regard.
Cheers
Rajesh
