Why not work to improve your credit rating and then get institutional financing cheaper than paying a hard money lender and possibly paying a hard money broker to broker the deal? You pay for good credit once, you pay for bad credit for the rest of your life. Good luck!
Please feel free to PM me with more details if you're interested in the latter.
If you don't have a trusted person to recommend a mortgage broker, you can do two things.
First, if you are buying a home, ask your Realtor for a recommendation. Any Realtor who has been in business for a while will have 2 or 3 folks to recommend based on a solid track record of prior performance with the Realtor's clients.
Second, contact your state's Mortgage Broker Association. I've attached the link for Michigan below. Most bona fide brokers will be members (but not always), and most members will be trustworthy (but not always).
