I am not really a fan of PPC ads for a towing company.  I honestly do not think they are worth the money.
You pay for every click regardless if they call you or just look at your website.
If they click your ad, call you and ask, “Where is my car?” you just paid to answer their question.

You would pay me to setup your campaign because you want my expertise in the towing industry to know what keywords you want to use and which ones you do not.
THIS IS VERY IMPORTANT.
You do not want to pay for keywords that are not relevant or people calling for toy tow trucks.  Google and bad planning will cost you money!

PRICES

YOU PAY GOOGLE DIRECTLY FOR ALL ADS .    YOU PAY ME TO MANAGE THE ACCOUNT
The cost of ads from Google are not set. It changes daily based on demand. Google auctions of the keywords so each day your number of ad impressions will vary based on your daily set budget.  You can set a daily or monthly budget and decide on if you want ads to show non stop till you hit your budget or staggered so it covers a 24 hour period.

Average click is 5.00 to 12.00 for a towing keyword

10 clicks at 5.00 average is 50.00 per day
50.00 x 5 days a week = 250.00 week
250.00 x 4 = 1000.00 month
1000.00 +25.00 = 1025.00 TOTAL per month on average

Google makes so much money selling ads that now if you spend more then $150.00 a month they will now setup your campaign for you.  YES, Google will Do my job for you for FREE.

I WOULD ADVISE YOU TO PAY ME TO SETUP YOUR ACCOUNT. THEN YOU CONTROL IT AFTER.
Google has an app that allows you to run the basic setup from your phone. They really make it SUPER easy to take your money.  I really recommend LOCAL SEARCH

YOU CAN TURN ON AND OFF WHEN YOU WANT THE ADS TO RUN. YOU DO NOT NEED TO PAY FOR ADS WHEN YOUR NOT WORKING
