We have the LLC to build business credit and also get expenses out of our names as they are on credit cards.

@Steve Vaughan is right on point per usual, shop local first build a relationship and if strategic default is in your cards yea not a good play here you'll sign a confession of judgement.    

They have one checking account or credit card for the business.

When I have had this situation, I communicate well expressing the urgency on my part, provide access to another unit (if I have a vacancy nearby), and may give them a gift card or something for their trouble.

I am familiar with contracting and flipping, but not so much with having a partner and "showing my cards" so to speak.  

Offline includes doing yellow letters, post cards, bandit signs, news paper ads, etc.There's an abundance of material on BP regarding all the methods I've mentioned, so just type in the search box which method you'd like to learn more about and learn that method really well before trying other forms of marketing. 

Also, free signs, leads, business card layouts, and website (currently beta).

Before you go, get some business cards from VistaPrint (nothing special, just name, phone number, and email) so you can hand them out to people at the meetings.

Meet the players, introduce yourself, get to know them, ask for cards, take them out to lunch.  

I also used a few credit cards and a 401k loan which is what contributed to my holding costs.
