I doubt you will find any hosting company that will modify any kind of script for you. For that you will need to pay a professional.
I have a VPS hosting account from a big company and worked with their support for almost a week to have all the requirements installed to run Vshare until I decided to get an account at Hostonnet.com. I can tell you I am very pleased with their shared plan and their server is very fast compared to my VPS host. Not only they can install the script for you but they can also upgrade it for a ridiculous price. They know the script and I am sure you can't beat this kind of support anywhere else for your Vshare website.
