[LAD] How to ask?

FOSS developers are so generous that all users are already in their debt and already I fear may have upset some by saying so. You/they have my admiration, but it doesn't seem enough and the debt remains. Occasionally I see an opportunity to help, if a developer hints they're near starving, or I can dispose of some hardware in someone's direction... But, to the point. I'm currently using a fabulous little suite of tools which were almost written for me by a gifted dev.. http://sed.free.fr/audiotag/ (although the version I have is 0.7) I clumsily and regrettably offered that despicable symbol of capitalism - money (or goods) to show appreciation. I don't even feel able to ask for more from sed and I said I would write a GUI and some database code to develop it to an actual application, but I can't, or I could, but it would be a mess which I could only keep to myself. It would be barely usable, even after a lot of head scratching. May I humbly ask how to ask to pay for some development? As my time runs out in old age, I'd much rather enjoy using software than experience the real discomfort I feel when I try to code, but having used it since the beginning, maybe I can see ways of using software more intuitively than some. I may well be the fastest audiotagger in the universe! How to proceed? I duckducked for Linux developers, but thought I should ask here first. -- Thanks for everything, regardless. John.
