Craigslist Account Password Changer Needed

I'm in need of a program to automatically change passwords to a list of craigslist accounts. I will also need the complete source code when the project is finished. ============================================================= Features needed: 1) Must be able to load a list of craigslist accounts in the following text file format; craigslistaccount1:password1 craigslistaccount2:password2 craigslistaccount3:password3 etc... ---------------- 2) Must be able to; (2a) Load a list of new passwords to change original passwords to -or- (2b) Randomly generate new passwords to change original passwords to (between 6 and 12 characters long) ---------------- 3) Must be able to choose one of the following options as a way to change my IP address; (3a) Load and use a list of private HTTP proxies when changing passwords. Every password changed needs to be done with the next proxy from the list. All proxies will have a username and password so it will need to be able to read them from a text file and use the corresponding username and password assigned to each proxy. Should loop back to the beginning of the list and start again when all the proxies have been used. -or- (3b) Allow me to execute/use a rasdial batch file/VBS script to change my IP via dialup. Sense dialup is so much slower I will want the ability to choose how many passwords for it to change before executing the batch file/VBS script each time. Needs to be able to wait for a designated amount of time after executing the script before trying to change the next password in order to give the dialup connection time to log in. ---------------- 4) Must clear cookies after each successful password change ---------------- 5) Must be able to randomly choose different user agents when changing passwords ---------------- 6) Must be able to automatically and continuously log each account into [login to view URL] then change it's password. I will also want the ability to change this URL in case the craigslist password change URL changes in the future ---------------- 7) Log every password change to a log file in real time in case of a system crash ============================================================= I need this program as quickly as possible (24-48 hours max)
