trust me shes super quick!! choose the 2nd option, i was able to get a response from her by 2/3 days max (only coz seller was busy and couldnt take the pics more quickly.
So you pay for the service first, then send her a message with your 'transaction number' and write in detail what youre looking for and that you need a quick response (just to remind her - but trust me she's very quick ) , also be prepared to get her to email you multiple times with every specific items. Like 'extreme close up of the zipper, 'Made in ' sign ' ect....
Let me know how it goes
