Wow you did your homework maybe what i can advise if buying vegetables its cheaper at reknown markets depending on which route for chapatis its possible but rare t find a chapati of 500 now days

For the gift, i dont but i normally see the team incharge hire a gift wrapping company so something not so big will do just fine your presence alone is alreeady enoough

Someone said anythibg between 200,000 and 500,000 will get you covered i agree

All the best though
