hi there,
I cant see the doc attached. but i reviewed your site, if there are any additional modules, then cost may vary.
we are magento experts, we can handle large scale as well as small scale web as well as dynamic projects.
you can check out our company portfolio about the webworks we have done, for more information.
If you want i can give client references, if needed.
We could put a time line only after exactly reviewing the project requirement analysis.
Please approve us to start the work asap.
Thanks
Neetha
