Hey there.
I noticed you only have a few generic bids from people who haven't even read your job description, so I decided to apply.
Now, here's the thing. The budget you have set is really really low for this kind of job, especially since you want multiple websites automated. How much time this would take would depend on how many websites really are in question, but, in any case, this is something I have done before and would be able to finish fairly quickly, hopefully. In fact, I have previously worked on sneaker bots, but I can't hand you that code, since it was done for other clients.
Anyway, I will be looking forward.
Wish you a good day.
Abdulah
