Need to add donation functionality on featured nodes

Hi ,

I am using blog content type in my site and any registered user can post blog. Blogs in my sites contain some valuable contents I need to add a donation options for blogs which are posted by some featured users or admin make them feature. So is there any available module using which I can add a donation widget to my featured blogs (admin can choose which blog is featured). I have seen lots of modules like donation and ubercart module but I don't think these are matched to my requirement (Or I couldn't use them properly).

Any help is much appreciated.
Thanks
