Bot to add to cart on pgg

Hello, I am looking for someone who is able to make a bot that will add a product to my shopping cart on pgg. Currently the situation is as follows. When there is an opportunity to buy, that is, when they add the goods (4 pm) the site is overloaded (thousands of hits in one moment, the servers can not stand). Once the goods are added, the "add to cart" button unlocks for us. At this point you can add. When we manage to refresh the page and see the button, when we click on it, by default the page does not load and we have to refresh it. When refreshing we have a message, "whether to resubmit", we have to approve.

The bot should: refresh the page and when the button is active, click it. Then continue refreshing until the page loads and the product is added to the cart. That's all.

I am waiting for a proposal. Budget unlimited.
