career in SD

I wish to make my career in SAP SD functional module, I hold an MBA in marketing from Bangalore University, having almost 4 years of experience in various sales departments across Pharma and Software industry. Currently working as an Inside Sales Coordinator in the direct Sales department of a Tier 1 software company, Siemens educational society have confirmed me as an eligible person to under go SD training based on my experience however, I don't have the requisite financial support neither i believe that I would manage to get 20 full working days leave from my company to attend the training program. So kindly suggest me if there is any other training institute in Bangalore which can give part time training as well as having genuine industry interface to help candidates atleast go for some entry level interviews.

Any form of advice/suggestion will be highly appreciated by me.
