Find Membership Component for Joomla 2.5

We would like to print membership cards, each card would have a username and password on it. Those cards would be given to our clients as a gift cards. Our clients would be able to receive 1 time only hotel discount, flower shop discount and other kind of discounts. Here is what we need from you :) Find a membership component that would require minimum customisation for the task (We already have one or two in mind). Customise this component in a way that would fit following scenario: Our customer goes to hotel and books a room, hotel receptionist would get this card, and enter our website to verify the discount. Receptionist would login on the website using Username and Password from the card. Then receptionist will write in the empty field name of the hotel. This name will be recorded and associated with username and password of the user. Each card would be active for half or one year. So as you can see there should be minimum programming and maximum knowledge and 4-5 hours of your time to change language file. If you are still puzzled, here is how we see it: We will be using membership and license component just as yootheme or other sites using it on their website. You have membership and after you have to specify on what URL this template, module, plugin or component is going to be used, so there receptionist of the hotel is going to specify HOTEL NAME. That is it. Basically your job is to install correct component and change language file. We will also ask you to make a small button on top right corner of our website. If you are interested in this project suggest component as you are bidding on the project. Most proper component and lowest bid with highest rank wins :)
