Need help with sending a cycle from Kolkata via Indian railways

I would like to know if anyone stays in Kolkata who can spare an hour or two for helping with my health need.
A mutual contact has a cycle but does not have the resources to take it to Indian railways parcel office to send to madurai junction.

The procedure is a few simple steps.

Need to take cycle from near bhownipore post office to howrah junction parcel officd.

Fill the form with details I provide and collect the receipt.

Send me the receipt via post.

Thanks in advance to anyone who can help.
I need to get back to cycling but the current frame is too high for my neck pain.

Those who have dealt with me can ping me in WhatsApp directly.
