老外的邮件看不懂

老外要的盒子市面上面没有，然后我跟他推荐了类似的盒子，同时也跟他说“Because the market do not he the same Mental Blank case with yours. I am very glad to ask our engineers to design the especial Mental Blank box for you. As a pay, are you willing to support for this design? ” 然后老外就给我回了个这个，其他的没了 “Ok don't worry I will try to source the black case and get back to you when I do for your ecig price ” 福友们觉得这个是个什么意思，怎么越看越不懂的样子。。。
