Hello sir,
I have read all 5 changes and there are some confusions in the point #1 and in point #5 if you can come up to chat?
Relevant Skills and Experience
I already have vast experience in prestashop and developed too many custom modules and also have modified core code / modules too... like orders, cart, checkout flow, payment gateways etc...
Proposed Milestones
$77 USD - PS Changes
Stay tuned, I'm still working on this proposal.
