How do I convince my parents to let me get a chinchilla?

I have been researching chinchillas for about 3 months now! its my birthday in 2 weeks and im trying to perswuade my mum (my dad doesnt realy mind if i get one but he wont say unless my mum agrees to let me get one!) to let me get a chinchilla as a present from my whole family? i have worked everything out i have a caged sorted i have found exotic vets and i will put any spare money i have into a Chinchilla fund for things like vets and food.... I have already: researched ALOT (3 months in total every night) i wrote a 8 page booklet about everything i know about chinchillas and reasons why i want one and where and how i can keep it my mum keeps on saying no and no! she was saying things like there smelly animals and that... Any ideas on how i can convince her? Thanks
