hi,
I am a medium level Magento expert and read your specifications, but it was very much broad in its aspect. If you can give more specifics like the brand name, themes if already purchased, your current Webspace capacity etc, I can give a more specific quote and time to complete the project.
Speaking more of your requirements, In India, Paypal doesnot work, but other payment gateways like payu, ebs etc do work, shipping is integrated inside Magento and doesnot require any specific configuration for it as well.
So we might follow these steps for you to understand our professionalism to your work
Install Magento (if not installed)
Install M2E Pro
Convert theme to HTML, Get your approval
Create Theme space in Magento
Convert HTML To Magento theme
Add functionalities to home page
Add functionalities to sub pages , view, checkout
Add Payment Gateway
Check site for errors,
Handover of project
Maintain for a free 1 month period
This is the standard procedure we follow durning any Magento theme development, and it takes from 10 to 20 working days to get a complete site on the server,
Please feel free to ask me any questions you have and will respond soon,
Best Regards,
TGS
