Hi there,
I have gone through your project details and understand your requirements. I have experience on dropshipping in Shopify. You asked that you need to import these 400 products within tonight. If you hire me now, I will do your work continuously until I finished your project. And I believe, I can complete the project within tonight.
Hire me immediately so that I can start right now and finish your job within your given time frame.
Let me help you. I will be glad if I can help you.
Best regards,
Sourav
