I dont have any experience with the links you provided.
But I do have experience with few companies I am giving you their Indore location, just give them a call and they will come to you personally to do all the formalities, and the cheque is always written on the name of AMC so no chance of fraud.

my experience with all three is good. they also have personal websites, they give you id and password so that you can view all the investments through them.
Just give them a call, tell them you have "X" amount to invest, Give your Professional prefix

and you will have a queue of advisors at your doorstep to serve you.
I started with NJ and then Karvy, my cousin too franchise of Prudent so I have experience of all three. Now a days I prefer to contact the local AMC head directly to put a large sum in, my personal folios are being managed at Birlasunlife, HDFC, and ICICI AMC local branch heads, but you need about a million bucks to get the response.

PS : Addition
You need a physical transaction with every AMC for the first time to enroll. (You will need Copy of a PAN Card, A cheque(to initiate the first transaction or first installment of SIP), Copy of a cheque or cancelled cheque to start ECS for SIP, and An address proof for KYC.)
After you get folio no. 48 hours in general will be the time you need (T + 2 days), you will get email with statement, use those details to register at their website and you will be able to handle all the information later online.
still online purchase of Mutual funds is not like e-commerce that you log in select a scheme and purchase, few AMCs do allow, few dont but I am sure with initiation in investment you are not looking at 2/3 AMCs at the max.
Feel free to call anytime for more information.
