Have A Meeting With A Firm That Does 1 Million a Year. Need Proposal and Presentation Help

A little background: My business partner and I started a digital marketing firm earlier this year and things have been going extremely well providing SEO and Social Media services. One thing that has always been a weakness of ours is proposals and presentations. Most of the clients we have gotten have been referrals and we have not had to really do any cold calling or talk to any cold leads as most have been referred to us from friends and are existing clients who have been really happy with the results they have gotten from us so far.

However, a friend of ours who knows the owner of this company setup a meeting for us in one week for a company that has over 100 million dollars a year in sales and we are freaking out! My main question is:

· Does anyone have any suggestions/resources for doing a killer presentation and proposal for SEO and Social Media Services?

· Does anyone have a killer presentation or proposal they would like to white label/give/sell to us?

Basically, this job would be for around $5,000 to $10,000 a month for services so having a tight proposal and presentation that stands out is absolutely essential. I know we can do a great job handling the workload and our team has been terrific so far.
Also, any experiences with high end proposals/presentations, advice, or words of wisdom would be extremely appreciated! Thanks.
