这句话有没有语法错误？

Question

Could you tell me what do you use it for and how many you actually need, so that we could indroduce some right style for you and quote a favourite price.

Answer 1

could you tell me 引出的句子是宾语从句，从句要用主谓宾语序，或者说是陈述语序（只要主句是疑问语序就可以了，从句不需要）；而且for what一般不分家，要写在一起；还有，这一句话主句是问句，所以句尾要用问号。也就是说，最起码这个句子应该是：Could you tell me for what you use it and how many you actually need, so that i could introduce some more suitable styles and quote the best prices?

Answer 2

Can you tell me how do you use it, and how much you actually need, therefore, we can take you indroduce some correct style and quote a favorite price
