Ok. Word of mouth/referrals take time to get around. I'm now just finishing my 3rd year and I work from home. Maybe your expectations are too high?
Yea it takes a while for word to spread and your reputation to grow. I used to think working out of my house hurt business but i can remember the last time someone didnt do with with a repair that wasnt just tire kicking away. THe ecomony is really tough right. Everyone is suffering from what i hear.
I went to a seminar about a year ago run by the SBA and they said like 50% of small business is run out of people homes. So it must be working for poeple.
What are your advertising channels. I find the adword brings in lots of business. Had 2 this week just from craigslist. Start and referral program. If something doesnt work try something else. The most important thing about business is learning how fail. It will happen. Dont let it get you done. Look at lisa(call that girl) she has been through some hard times but is making the best of it and actually happier and making more money.
