I have many clients that are running my latest premium plugins which helps me offset the time it takes to develop and support my general release plugins. I've not made a big announcement or set them up for online purchase because I'm just soo busy. The time and effort required to get the marketing and online purchase scripts setup just does not justify the time right now. I am finding those that are serious about buying one of my plugins have no issues contacting me. I generally reply within the hour and have the transaction completed and download in their hands quickly.
So if your interested - please don't hesitate to contact me. I'm holding off making any big changes on this site or integrating a shopping cart app that supports digital downloads for now.
I also am available to do installs, custom modifications and projects. I have a number of larger projects underway for clients but can certainly handle your inquiry and help scope out the project. Projects often slide around so it's good to have a combination of small and larger projects.
