Trying to be a sponsor and can't get information

[Padholdr]

I would really like to be a sponsor, especially under the Playbook section. My company manufactures Playbook holders for home and car. We have an elite product, that already does well with iPad and Xoom. We are currently the sponsor on ipadforums.net and xoomforum.com. I've sent multiple emails, and contacted an administrator and havent had any luck.
Thanks in advance
Jim
