Neopets autobuyer?

[Romanianz]

For years I wondered what it would take to make one of those things...
I've stopped playing it ages ago but I wouldn't mind leaving an autobuyer on just to see how far it could go.

What would it take to make such a program?

For those that don't know how the system works...
Basically, at random time intervals, a 'shop' will restock it's items.
The bot would need to be able to refresh the page at random times (not too far apart but too many and you get restock banned). It would then have to pick out an item if the shop got refreshed (the item consists of a small picture, followed by some text Name if Item, Quantity and Price. Not all things are good, so it would have to go for specific things.

Shop interface:


In order to buy it, it would have to... Click the item, then press enter or click a confirmation screen asking to buy it. It would then have to click on a price field and type in the price needed for the item (or somewhere in it's vecinity) and it would then have to click a custom captcha created by neopets. It doesn't work with funky text like the normal ones do, it works through blurred out pictures of 'neopets' on a background, and you must click the neopets in order for it to actually buy the item.

Price field and Capcha:


I know they exist, I have used one in the past. Anyone happen to have a working one laying around or know how much experience would be needed to make such a thing?
