Yeah, I was thinking the same thing myself, after I googled how to clean a camera sensor. I'll pay for it, do you know how often it should be done?
I will test some images shooting RAW and see if that improves the acceptance rate at 100% size. If it just means I have to recolour the image I will probably give it a miss I can do that even as a jpeg. I come from a background of working to tight deadlines and not many people in a real job had endless time and money to achieve perceived perfection. They just do the best they can with the constraints and budgets they have.
Its nice to that have you survived the harshness of this forum - even excelling as a forum member! I personally don't need it, I did not get from my creative superiors in the work place and nor do I need it here. Also people on this forum are not adverse to giving bad advice and bum steers.
Thanks for taking the time, cheers
