Hi,
I'm a web developer having 7+ years of experience with good knowledge of WordPress and Joomla. During my work period, i have developed and designed many eCommerce and non-eCommerce responsive business websites, upgraded and migrated websites and resolved many issues.
I have read you requirements and check the doc also. I can do this work, but cost will be higher than your budget. If you're agreed with that then we can discuss more on this project.
Looks forward to hear from you.
Thanks.
