Donations page on Word Press- Non profit org

We are in the process of starting a non profit organization. We are looking for a donations page to be placed on our website, [login to view URL] (It is currently unfinished). We do not want an external url page from an outside donations website but one that uses our domain. We need multiple means of payment, not just a paypal button. In our view, just the paypal looks unprofessional. We have enclosed a link to a donations page we like, and would be looking for something like that for our website. It has to be secure. In the link below, the section that says architecture of a donations page, that is what we are looking for. With the option of recurring payments and single payments. Credit card payments and not just paypal. [login to view URL] If you feel you can do this, I am happy to talk more with you. Thanks.
