Can your father afford to spend Rs. 110000 and get almost nothing back? What effect would that have on your relationship with him? Because getting almost nothing back is the most likely outcome.
How many copies will you have to sell to show a profit? I don't know if India is different, but in Britain and America, the average "pay to publish" novel sells about 40 copies. If you don't believe me, go to your nearest large bookshop. How many romantic thrillers (or novels of any kind) can you find that were published by Leadstart? I'll be astonished if you find any. That means Leadstart can't get their books into bookshops (actually, they don't even try, because that's not what their business is). That means they won't get *your* book into bookshops.
Maybe Leadstart's books are available for sale online. (I don't know if India has any big online bookshops like Amazon.) But even if they are available, hardly anyone will buy them. The publisher does little or no marketing, so hardly anybody knows the book exists. Anybody who recognises the publisher's name knows that they'll print anything, no matter how bad, as long as someone pays for it.
The publishers who rejected you are in the business of selling books to readers. Publishers like Leadstart are in the business of selling books to writers. If you understand that, everything else will make sense.
Incidentally, when they said Rs. 110000 was 50% of the cost? They were lying - it's 100%. Even if they were telling the truth, how much marketing do you think that much money will buy?
My advice? Learn how to write a book that's good enough to be published by someone who doesn't want you to pay. If that sounds like a lot of work, it is. Publishers who don't expect you to pay them publish maybe one in a hundred of the books they receive from authors.
