Dear Client, I write a app to do it for you and use bulk insert for fast operation , I have a question do you need GUI for app or just console app ? we've more than 10 years of experience in developing Apps and you certainly can trust me on this one .
please contact me in the chat section to give more info on the app itself and also share the design as well .
we are looking forward to hearing from you soon.
Thank you for your time
