autoresponder lead import via email function or auto optin function - repost

Hi, I am looking for someone that can build a custom application which is hosted on my own server which allows you to upload as many leads as you want to the software, and then passes them to ANY Autorespoinder (GetResponse, Aweber, any AR of your choice in a completely natural and undetectable way. The script should have multiple security features built in like cloaking for all of the major Autoresponder companies and more. The script should be able to handle 1million+ email addresses no problem and should be able to be installed on as many servers i want. the only way i know this can work is for it to use the email subscribe option. however, if there is a way to make the software opt in the leads into one of my pages randomly to get the leads into the autoresponder account. please share your thoughts on this and if you have already built something like this already. if it uses the email subscribe option, it should work like this: 1. i upload the lists. 2. an email gets sent to my autoresponder email (example: listname AT [login to view URL] etc.) 3. it automatically subscribes the user who sent the email to my list and does this randomly each day until the entire list is imported. If there is a software or script that i can have built that would automate this process that would be perfect. the main thing is i want to make sure this script works in a way which is impossible to notice for the AR (it looks 100% natural). Please send me your bid and how you intend to make this work. Thanks.
