Don't mean to step on your toes, or make it sound like you aren't doing enough, fast enough.
I just meant it as encouragement in your business growth. Logos or a dedicated business line don't mean anything about quality, necessarily. Short term signs are available really inexpensively. Could just be services available, with or without a phone number. Maybe you just go word of mouth, or stick to the people that approach you while working as they can see your work and are likely within your target work area. I have signs on my trucks that say "Ask us about your trees!", as an invitation of sorts that says that they aren't going to be bothering us (necessarily) by approaching us while working.
I don't have a personal phone seperate from my business phone. I just use on mobile phone for all my needs.
People almost always get a kick out of it when the conversation goes somthing like, "...okay, I'll be glad to meet with you. I don't have paper and pen available to me right now because I'm 60' up a _______ tree. So could you call back and leave me your contact info on the vm?"
"What? You're in a tree? Oh I didn't mean to disturb you... "
Me: "No problem, I'm just hanging out. I wouldn't have picked up if I was too busy. I'm the principle climber and am out on every job to ensure safety and quality, so sometimes I answer the phone from the tree."
I'm sure it would be strange to hear the person answering the phone is in a tree if they were calling roto-rooter.
