一段英语,麻烦改下语法错误
Michael,
I spoke to Lena again today about the request to help me with the seminar,and as this is conflict with our event,Our help will be limited to helping with having some marketing material ready for the seminar and arranging for some printing services here,that id going to be much easier and cheaper for Jason this way.
It is not my intention to make money by providing marketing support service,and we will be very happy if we can limit this as much as possible,as we have our own sales support objectives to meet.But,should we are required to do that,we are going to loose money doing it.As we have calculated it before in relation to some of the development projects,own costs per hour are
$30 and if we charge that,we do not make any money.$30 will be the hourly rate we will invoice Jason for the services,plus any related expenses.I trust this is fair..
Thank you,
Philipp
