Hey there,
My name is Sam, I have a Master's in Computer Science from DePaul University, Chicago and have been doing web development with my small team ever since I left my job at CDW, Madison. I have worked with clients and companies including Sears, Target, punch stock, tire rack, NASDAQ and Harley Davidson.
It generally happens with old extensions, which are no more maintained by the original developer or has been developed for a specific website only.
To ensure it can work with Latest Magento Version, I will need to check the extension code to check if this code can be updated to make it work with Magento.
What I could offer you is an entirely new extension, which will take care of all your needs. To give a price, we need to discuss the requirements first. I can only quote after checking on the requirements...
We can discuss the work over a Skype / Phone call. You can contact me at '+1 630 847 0018' or you can also contact me via Skype 'datasofttechnology'.
I am new to Freelancer, but I can share reference of my 9+ year long career in eCommerce with you, and you can also check Elance profile which has 5* and tons of successful job.
Thanks,
Sam
