Samridha, tell them that you believe in quality work & you can contribute more then their expectation. You can gel up well with other collegues which will support the team as whole. Try reminding them about your stronger skills which will serve them as an added advantage.

Think of all the positive traits in your character and find items where you will be able to contribute to the company. Always try this approach - see how what are the maximum number of things that you can give them for the package that they offer; not what is the minimum.
