Build a Bot - UK BASED DEVELOPERS ONLY.

I need a bot built to go through certain links on the backend admin area of large UK website that I have access too. The programme needs to have a 'homepage' where I can log in with a username and password (the username & password's change regularly for the website we will be accessing). The programme then needs to go through various links within an admin area on the site and it will need to be repeated on a number of occasions. I had this bot built by another Freelancer about a year ago, but the website I am trying to access has now upgraded its security settings and will only allow access from certain computers after clicking an authorisation link and ONLY FROM PCs IN THE UK. The current bot gets blocked because it is not deemed as coming from my PC, so I need someone to make sure that on clicking the authorisation link, it will work properly. I do not have the source code for the bot that was built last year, but I can let you have access to the programme so you can see how it works. It cost me $250 a year ago so this is what I will be looking to pay again for this sort of project. Once completed, I would like the source code and I would like this to be written in either C# or Java Thank you
