Hi, Could you please let me know about the theme to be installed and the tweaks you need so that I can review it to provide you an exact estimation.
I have expertise with Magento 2.0 set-up & implementations and configuration, design custom theme/ template from scratch, Customize existing themes, create custom extensions/ plugins, integrate 3rd party tools and APIs, Shopping cart integration etc.
It would be great, if we can have a meeting and discuss the position in details. I will provide you with services that will ensure a long term professional alliance with you. Look forward to get your positive response.
Thanks
