Thanks for your input!
I think I'm going to start of small and just test the waters with a $1k budget. If it goes well I'll scale it up.
Is it possible for you to talk to their old customers on EL?. There are companies here that offer their service, usually it s at a flat rate, or a percentage of the spend. It s expensive to hire someone for this, and if you know how to do it correctly you can literally name your price. Many businesses get all their traffic online, and are happy to spend $5000 each month and make back $15,000.
If you want to do it yourself, set up a small SEO company website, and contact Engage for Google. Let the know that you are a new service company starting out, and you want to register. They will call and talk to you on the phone, you spiel is that you started building websites for friends and family, it snow balled and is turning into a business, and you want to do it professionally. I got approved quite easily.
If you get accepted you will be eligible to take the official course and get certified in providing PPC services.
This training is free, and you get a Google certification, as well as a through, if basic, understanding of adwords PPC best practices and system.
If you decide to use a vendor, you can tell a little about them by asking a few questions. How often do they personally look at your campaigns? What tools do they use? Do they split test? Do they tweak ads? It must be watched like a hawk, and you must track and tweak everything, and split testing and tweaking never stops.
If they do not know this, drop them as a candidate.
With PPC you have to get your ad to work in converting viewers to visitors, then you have to get your landing age to convert these visitors into customers. Keep your spend low until the ad really starts converting. The day your ad is finally working, you will get a rush of traffic, and if your landing page is not converting yet, you will spend every dime in your account if you are not careful.
After you ads are converting, drive at least 1000 (a few thousand is better) people to your site and look at the conversion rate. If you did not get a 1% conversion rate something is wrong, generally speaking.so you might you need to work on the landing page.
The person running your campaign needs to understand ad groups, quality score, and how to analyze the tracking information. They need to know to stop a campaign that does not do well in the evening, and restart it in the morning before the lunch crowd if that campaign wastes money at night but converts during the lunch break.
They need to understand that you want maximum exposure, not the top spot, and adjust your campaign accordingly, Often the 3rd spot will out perform the top two, and your ad will advance up the list as the other customers spend for the day expires anyway. You do not need to buy your ads for a premium price, you get charged by the click.
Good luck
