Hello Sir,
I have done similar tasks before and have installed various scripts for my clients at freelancer.com as well as individually at my work place. I can troubleshoot various problems if it comes while installing the script and can ensure the best and required output.
If you hire me to install the script, you can pay me after I complete the installation and you are satisfied with it.
In case if you need any clarification or want to discuss anything with me, please do contact me and I would be happy to answer and discuss with you.
Regards,
Prashant Gautam
