I need to develop a Shopify store in UK from India for my friend. She is running a business in UK.

I need to develop a shopify store in UK from India. So how should be my possible approach? Should I subscribe for a Shopify plan from India in Rs, or ask her purchase it from UK. What are the things that I should take care of? Is there any possible issues or problems that would occur?
Guide me on how to setup a store for a business in another country. 

Thank You
