We have an email address on the landing page for folks like you -- [email protected] -- ping us, send us details, we'll get you over and take care of you. It's really more for recommending the intermediaries but it's a way to contact us -- so take the initiative :) The sentiment here is largely correct -- accelerators, VC's and others provide a great way to prevent fraud and other issues that programs like these deal with. We also offer $500 credit vouchers for folks who want to tinker and we are working on other ways (stay tuned) for people who want to evaluate for free to do so.
Hope this helps --
-Brian head of marketing, google cloud platform
