Good day
Bots like these are my speciality. You have some unique challenges but I believe I can get around it.
Basically I would create a Windows desktop application (using VB.Net) with a built-in browser that will simulate all the clicks, etc. that you would normally do by hand.
I will really need to analyze the website and it's source code to be 100% sure this is achievable, if at all possible please give me access to the site so that I can have a closer look.
Kindly check my profile's record and reviews, I'm sure you'll see that I am a safe bet and will only deliver 100% perfect results. My price is always negotiable.
Looking forward to doing business with you!
Louis
