Authorize.net ARB Integration - Tell me how to do it

The project is simple. Integrate [login to view URL] - ARB to a custom project. You will NOT need to go through any fancy codes or any shopping cart. You will simply be working from a payment form. The form is also ready. It has all the validations etc. You will need to tweak (eg. get the shipping address off) the form to suit your needs. SCOPE OF THE PROJECT: [a] ARB Integration - for the subscription purpose. [b] Set Silent Post - for updating the status of the subscriptions. [c] You will tell me how to do it / or do it yourself. I prefer doing it myself. Also you will tell me how to set up the SSL. [d] The project will be a success when a user can put cc info and the form successfully makes a payment or fails to do so, and the appropriate success/failure pages are shown, and also that the silent post url are also working properly - and you preferably guide me how to do that or do that yourself if need be. [e] You will not need to update any database or anything - if you have the mysql tables for entering the payment details that is good. There will be 30 days of Free Trial before a user is charged. Will provide you more details once we are talking. If you read this far = type : "HELLO I am an expert in ARB Integration!" before writing anything you write. Needless to say that someone who has not Integrated ARB into custom php code, like this before, need not apply. Budget Less than 50USD URGENT! Thanks
