“The more work you do, the more work you get”.
But how do you get the first one?
As for stopping in at REA Offices:
When Jehovah Witnesses show up at your door, how do you handle it?
REA’s are professional marketers for the most part. Do they have time for you?
What makes you better than the guys they use now?
No one wants to break what works. You have to be pretty good for them to break the glass!
So look at your presentation through their eyes. You need to find the void in their business plan. You won’t do that with a business card (though that is your first impression, which keeps the cards out of the closest trashcan).
No one is hunting for you. You can hire a marketing company, like Angie’s List or something. They will get you on the list for the “Race to the bottom”. The fight for who can be the cheapest.
No one “selects you” from your advertisement attempts. They are “eliminating” you from the list. Whoever doesn’t get canceled, gets the opportunity for them to dig deeper for things to delete you for. They will hopefully come across something they can relate to and decide they want to invest in your service. Remember, this is a “Service Business”, not a “Retail Business”. Do not use any Retail strategy like Black Friday Deals, or 20% off for this week alone. The clock is counting down. It might work in your mind, but not theirs.
Don’t list your Inspection Fees. There are no two houses alike, so there is no one fee that fits all. Inspectors do it, but remember, you have taxes to pay in April! If your fee is above the other FNG, they won’t even click the “Next” button. The reason you are advertising a service is to make the phone ring. You can’t sell, if you can’t connect with the caller. Then you need to answer the phone correctly. Who likes getting a Call Center? What is your reply to “How much do you charge”? Many Inspectors have said they hate advertising that doesn’t list prices. Well, they are as stupid as a home buyer that only wants a cheep job. You don’t need these clients for anything, except to feed your family. If you can’t get through the next year without work, your business plan sucks.
I did not answer how you can be a 90-day wonder, because it is more critical of what you should not do, than what you should do.
If you have time and money in hand, I recommend you enroll in a Real Estate pre-licensing course, and find a Real Estate Company that will sponsor you for their pre-hiring course. Get the books they use to learn REA marketing and study them. You will learn the marketing you need. How to overcome objections. How to use the alternative of choice. Understand the REA position in a home sale. Get to know new and experienced REA’s that don’t need to know your HI Goals. You may even want to take the REA test and fail it, and say this is not for me, I think I’ll look at a Home Inspection.
In order to do this, you willl meet the princible broker, training brokers (who do the recommendig of sub contractors), seasoned agents and new agents who may produce some time down the road. Maybe, if you are still both at it.
You need to be asking for what you need and for help, not telling how you are God’s gift to the Inspection Industry. “Just look at all those stickers I got on my website”!
Does the Agent have issues with Inspections that you can legally overcome? You need help, and so do they. Otherwise, you’re just a vacuum cleaner salesman.
I did something like this, over a lifetime, but I did pass the test and sold a few houses to feed the family till my wife got out of medical school. I never did the marketing you are looking at. On my week one, I had so many high-end houses to inspect, I had to get a hotel room nearest my next day’s inspections. I did not look for the REA, they found me because they knew me and my background in Real Estate already. They were looking for someone to make their required inspections for their relocation clients as smooth as possible. 
It’s what made my business kick-off on day one. Take of it what you wish. Your results may differ…
