I am a part of some local entrepreneur groups and they're great but have very strict guidelines on how to promote your own endeavors.

Contrary to popular belief, this is not set because I believe it will give me a higher return.

OR, watch a few YouTube videos  produced for self promotions and write a check and then pray t all works out!!!

a little self promotion spotted, but it's all good :) I do agree with Cassi regarding the overall OKC market.

We are planning to run the promotion through flyers providing clients credits towards closing.

I have seen one of their promotional videos which is full of the same guru bunk I see elsewhere. 

Definitely echo the sentiments that $0 money investing is much more myth and marketing snake oil than being plausible.Closest thing I know to quick easy funding is a 0 fee, 0% credit card balance transfer but not everyone can command 30K plus credit limits and I wouldnt recommend that path unless you are equipped to handle that debt once the promotional APR expires

I can't put them in this post because they have some "promotional" phrasing included (I created them for customers) that I encourage you ignore.

Hint: contrary to common belief it's not the fees. ;-) 

for the completed survey (done via email/Google survey to limit paperwork/printing fees/hassle) AND make the gift card/certificate to the town's greasy spoon or similar, and ask the greasy spoon to promote you in exchange for buying all the gift cards!!
