We are Prashushi, a group of coding enthusiasts, who will try and find out the best solution for your requirements, in a reasonable time, in an economical way.
You will need to pay us 30% fee in advance, and we will ensure that your requirements are fulfilled on time.
If we are not able to complete on promised time, we will give you 10% rebate (ON PROMISED AMOUNT) per day for 7 days, after which, we will charge you NOTHING beyond the initial 30%.
This rebate period will start the day after the promised deadline, and will continue for next 7 days.
E.g. If we promised to deliver on 8th Sept 2015, and we are unable to deliver by 8th September, then you get 10% rebate per day from 9th Sept 2015 till 15th Sept 2015, beyond which, we will not charge you anything except your initial payment of 30% of the fee.
If we are unable to deliver, we will return your full money. This is highly unlikely to happen, as we undertake projects according to our potential and don't over estimate ourselves.
We would need more information about the SDK you are using.
PS - The time limit mentioned here is not final, until we are not completely clear regarding the requirements in our subsequent communication. Please contact for more details.
