First of all thank you for your understanding and the discount you provided. 
I appreciate your help on this. 
But still we are very far away from what we can really pay. 
Still the amount you mentioned after the discount is very hard to find in cash.
We need to take some serious IT decisions tomorrow as most consultants advised us to format and start from latest offline files which will take several days.
So please if you can give us a more grounded financial proposal do so since the purpose here is to see if we can use your services.
