Depends upon a lot of factors, easy or realatively easy fixes are Style and Fitness, spitting game depends upon a lot of variables.
1. Fitness : Diet, Gym or rather just cardio to burn that fat. etc
2. Style: Even spending $ 500 his wardrobe can be fixed, Nice pair of Selvedge Jeans, Shoes, V neck and a Sports Coat, of course with a Pocket Square.
You said he is balding, I say have him shave his head and grow a short beard and or a goatee, see which works better with his vibe.
Easy personal grooming stuff, cleaning nose and ear hair, whitening the teeth, tell him to stop eating
"Heeng", english name for the spice is "Asafoetida". That stuff stinks, body odor will Improve by quitting some spices.
3. Game: This depends upon his desire to learn game, If he has a burning desire then it's easy, If he's on the fence it's a serious task.
Internal game Improvement and shedding the Indian pre progamming will have to be done first.
What he is trying to achieve will not happen in a month or two but at least a couple of years and he will have to lower his standards in the beginning and then he can work his way up.
WIA mentioned a modest Apt, I would say spruce up the Apt Lighting, Art, Pictures etc. There is thread on the forum about it
Needless to say he should be on the RVF and more ........
How do I know it's doable, I did it. In my Initial posts here in 2010 I posted
"how can I bang 21 y/o blondes at the age of 37 + being an Indian looking guy", people laughed at me, some gave props for setting such an enormous task. I did it and now I say College girls 18-21 are easier then a 26 y/o game hardened girl in USA. Granted I wasn't Chubby or balding but I had all the problems that a newb can have except Approach Anxiety.
WIA if you end up taking him up on the offer, give me a shout I should be able to help with some nuances that people not familiar with Indian culture might not understand.
