Magento Finance Providers Module development

I have a module in Magento admin by which I can save my different finance providers name data like name URL logo active or not. Now I need to create a payment extension which will appear at the time of order payment section. If a user selects finance as the payment method then the active finance providers will appear as select with options. When selecting any of the options then the logo will display beside and an Apply button will appear with the saved URL. When User clicks on the Apply button then an iframe will appear with that URL. Please write "Module and Extension Development" at the beginning of your message. This is the basic idea of the project.
