I am willing to be a software tester and even software editor. I have written over 200 user reviews for Softonic.com with almost 250,000 views and an approval rating of 90% (3,445 out of 3,825) since October 2009.
But for me to test the effectiveness of your Malware engine you will need to find the best test viruses out there and let me test it's rate verse the competitors.
I am not sold on your defragger yet, it would be nice if you could combine the power of Puran Defrag with the speed of Auslogics Disk Defrag. As for the cleaning goes, I'd like to suggestion you message PC World and have them test your optimizer against CCleaner, 360Amigo and Advanced SystemCare. To see not only how it cleans vs the others but also how it affects the overall computer performance as well. PC World uses a top notch benchmarking tool so you rank high on their benchmark test and you're gonna be recommended off the bat.
Also as a former tops sales person I would also be happy to try and help sell your paid products. But they would have to live up to my standards first. I am very anal so to speak on the quality of products I recommend to others.
So basically with me you can get a software tester, editor and sales person. If you need help that is.
