Go to open house that the agents are having and talk with them. Tell them a few changes that might help sell this home. I feel a real estate agent should not put themself in the business of telling a home owner their is something wrong with their home. This can upset a homeowner that they don't like their home. Leave this job to a stager.
Now, you might have better luck if you focus your home staging marketing to the more expensive neighborhoods. Perhaps $150,000 and above. You'll want to walk those neighborhoods regularly and introduce your self to them. Hand out flyers, brochures, business cards, and anything else that might help them remember you when they decide to sell their house.
You should try to get on really good terms with all the local Real Estate Agents. Visit their brokerages, remember their names if you want them you remember yours, be willing to speak at their sales meetings, and leave them plenty of marketing material that they can give to clients.
You'll also want to be careful about your degree in college. Do I care if my home stagger has a business degree?...Not really. Would I be impressed by a degree in Interior Design...YES. A business degree will help you run the business when you have employees that your paying, payroll, taxes, management, etc.. But impressive work and developing a portfolio, will comes first and you will be in competition with other home stagers.
Starting a business is much like being in sales, your product is yourself. Good luck.
