Mile high takes a while to answer emails, but in time they will usually get to you. However, I would order Your SPUHR mount from their website with a credit card. If you do not have a credit card why not give the money to a friend who does and use his? Failing all else if you really need it right away, and you are willing to pay a big premium for the trouble, I am sure that there are several of us who might sell you ours.
It seems to me that you need to also figure out a few more things before you are really ready to order. For example do you need Picatinny mount or a cantilevered mount.
Lacking further info, it seems best to use a credit card. If you are in no hurry, Mile High will get back to you in a week or so.
