Hello Sir/Madam,
I have designed and developed many eCommerce websites, which are currently running online as business.
For those websites/project I used Magento instead of Joomla, because Magento has almost all options, if you ask me any function/system I am sure I will be able to answer within Magento.
Please check my private message for my top websites from portfolio.
I would like to build this project on Magento, if you allow me and I am sure, there will not be a single complaint about it from your side.
My standard pricing strategy:
20% on project initiating
60% when complete Magento website is done and lived at our demo server for review
20% after I live all things at your website
Thank you!
