Hello,
I have 6+ years of experience in creating installers using NSIS. I have created more than 40 installers so far. Please check out our work profile here on Freelancer to see the projects we have executed. We have also developed installers for various clients on Elance (profile "genesisbuzz" for your reference).
Please let us know if you would like to see demo of my work and have any questions.
Thanks & Regards,
Vighnesh
