Buddypress credit shopping cart and PDF creation

We are looking for someone to develop a credit system shopping cart for our buddypress site. Our site is to be a social network for actors and advertisers. The actors place their profile on the site and advertisers can place the auditions on there for free, this all works fine under buddypress. What we need is a shopping cart system, where both user types can purchase credits on the site. These credits are then exchanged for purchasing contact details from the actor profiles. This will be the users workflow: 1. the user purchases credits. There will be 4 main options: 5 credits / 10 credits / 25 credits / 50 credits. Each at a different cost. This process needs to work like a shopping cart with paypal as the only payment option for now. 2. This user then browses the site for a actor that they want to contact and clicks on the contact member button on their profile. 3. After confirming that they want to use their pre-purchased credits, we then need the member profiles selected to be created into a PDF document that can then be downloaded. This PDF will contain 2 pages, first is a full page of the users profile picture and the second is of the profile information that the member has filled out. (These PDF needs to be created on the fly by the system so that when the user downloads them they are up to date with what is on the site.) 4. These purchases then need to be available on the users admin where they can re-download if they need to. The above needs to be as a plugin so that we can implement it onto other wordpress/buddypress sites. If this isn't possible we would need detailed instructions on how this can be implemented onto other sites. As an example of the credit system please look at how [login to view URL] works. If you are unfamiliar with this please let us know. Along with the above we also need a couple of tweaks to the current site. 1. New group creation fields to be added (these will be supplied) 2. Certain profile fields need to be hidden, ie contact details 3. The user type "advertiser" needs to have a different profile to the "actor" profile 4. Date of birth number output on the profiles need to be converted into an age and not a date 5. Profile tabs Gallery and Jobs need to swap around 6. An advanced search for the talent directory and the auditions & jobs pages are needed (fields will be supplied) This should be all but there may be a couple of extra small bits. We are looking to find someone that we will be able to work with in the future with as we are hoping to produce a number of website along these lines.
