How do I double revenues in a short period of time?

Advice will vary depending on market and the service you are providing repair service in. If this is B2B service then I'd recommend you purchase a call list in your area from a reputable source and get yourself on the phone. Learn to sell your service so you can train your sales people. I'd recommend an auto dialer like Five9 as you grow but it doesn't hurt even if you are the only sales person. If this is B2C then you need to get on Yelp and work up your existing book of business to leave reviews. I worked with a professional service company in the midwest that opened for business in 2013 and did over $1.5M in sales their first 10 months thanks to Yelp reviews alone.

Use the local free print classifieds to quickly reach your target audience very inexpensively. Running a local ad there will also get your ad online where it will be seen everywhere including in adjoining locations.

Remember that you can reach different audiences in print than online with some overlap, so be sure to advertise in whichever editions are likely to come to your new location.

Here are some sites you should consider:

American Classifieds (Thrifty Nickel)

Pennysaver
http://www.pennysaverusa.com/classifieds/usa/

Look for any other free classifieds in your area and use them. Check to see if there is a local newspaper in the new area. They may have a weekly special mailing they do to all the homes in their area or at least all the subscribers. (Some actually mail every home in their area - this is a cost effective way to get visibility there.)

Next, get that location listed on Google Plus Places

Use Universal Business Listings to get your locations listed in all the other important directories and quickly added to the databases that feed cell phone directory and GPS systems. This Case Study shows how effectively that can work for you: http://growmap.com/local-search-ubl-case-study/

Share something in print (flyers, business cards) for the new location on the checkout counter of the original locations. This will allow existing customers to spread the word for you in the new area.

The fastest way in all of business to double revenue is to increase your price. Try doubling your price and see how many customers leave. If less than 50% leave then you just made money!!

This is technically called elasticity of demand and without getting all economics gangster on you, it's part of the 4 (or 5) Ps of marketing.

There was a recent article about an ecommerce retailer who actually increased prices 5% on Black Friday while everyone else was discounting. They made more money this year than last and didn't lose any customers. In this case, most people's elasticity of demand wasn't sensitive enough to the price change for it to make a world of difference.

It's up to you to find the optimal price point that maximizes Price * Quantity.
