Need to make a simple bot for auto surfing ads and bypass capchas

I have a traffic exchange site that i need a simple bot for that site. What the bot does? Make the bot like a web browser. Auto remember username and password after manual typed, and next time it will auto log in based on username and password. Auto go to the "Surf Works Offered" page and claim a relax position if there is available. Auto go to the surf ads page. The surf ads page is already auto surfing so no needs to make it more automatic, after 20 seconds of the timer, it will ask a math capcha, auto remember the result of that math capcha after manual answer, and next time when it meets the same math capcha, then it will automatic answer for the same result of that math capcha. Auto click the button "View Next Ad" Auto finish at 25 ads, go back to the "Surf Works Offered" page, and the cycle continues. The bot must be editable for sources or codes for prevent the site changes. The price for this project is range from $30 to $50.
