Daniel - no, Veeam reseller will not help you with this. Manual approval is possible only for Veeam ProPartners (by contacting their respective inside team at Veeam). Also, major accounts may try luck contacting their corporate account manager at Veeam.
For everyone else, the approval procedure is built around automated scoring system (I explained this in details in the weekly forum digest 2 weeks ago). We have a few thousands registered for beta now, and of course we will not approve everyone - only selected applicants with highest score will be approved, may be 10% or less. That reminds me I should make this topic non-sticky.
You can also try and get the invite from another beta applicant (everyone accepted into beta gets additional invites he or she can share).
