Dear Sir,
I have looked into the model site you provided and confident that we can develop a better site. For shopping cart we'll use open cart with paypal checkout and comfortable with rest of the features like uploading images, videos etc.
Highly interested and entirely capable to make this project a success story. If you could consider us for the job, will be happy to discuss further details in PM.
Looking forward to hearing from you.
Regards,
Farrukh
