Magazine subscription system and e-Commerce

My name I Leonardo, I the owner of TattooistArt, in which is a electronic magazine. For the moment the e-MAg is FREE, but I want to implement a payment system to my website and a subscription option, as from October I will have a printed version also. I would like you to have a look at this website payment system, as they have a similar e-Mag as mine and I would like to have something similar to their payment and subscription. Website: [login to view URL] What I am looking for: e-Shop where member can buy the printed version online and the e-Mag version Subscription option ??" so member can buy a 3-6-12 month subscription membershuo. When doing so they will have a log in access from where they can download the month’s issue. When they buy subscribe they will have to choose MAC/PC platform so that way it will only be available the platform they’ve chose to download. Also I want a system that doesn’t allow multiple downloads, once done show on their account that it have been download and so not allow download of the same issue again. So that way people don’t give their log in details to friends to download it. Attached is a picture of the download are for subscription, each month the magazine is automatically added to the members page so they can download it. Buy subscription. What I need: Again similar to the website I mentioned above, please check them out and click on the “ Buy 1 year membership?? button. I want something similar to their: starting from ending from - platform?? mac/pc ??" Version: printed/e-Mag /both and the toehr details. How long would it take to be coded? Around how much would it cost? More will be implemented in the future, like forum etc… Hope to hear from you. p.s.
