Checking to see if request for quote has been received

I sent in a request for a quote on custom code last Monday.  I understand that such an quote might not be ready just yet but I have not received any confirmation that it has been received.  As I wasn't sure what vehicle such a request should use, forum or ticket or email, I opted for email.  Plese let me know if it should be send in another fashion.  I am anxious to know if this might even be a possibility or if I will have to find a workaround.
