Well I'm glad we inspired you, but in reality inspiration doesn't get the job done. Most people who want to get into the Lawn Care business try to break into it with a minimal investment, I mean everybody has to start somewhere right. The only problem with that theory is the the greatest percentage of those guys for one reason or another end up leaving because they find out it's not as easy as it seems and they can't compete with the business across the street that's prepared for any job the client can throw at them and do it at a price they can afford and are willing to cut your throat in a heartbeat to get your account. ( I'm experienced in that...) The days of the mow and go guys are basically gone unless you like doing foreclosures. If you're considering getting into the lawn business you better consider a sizable investment in equipment to do the job people want to have done.
You say you have spent some time diving around looking at the quality of work some of these large operations are doing and to say the very least your not impressed, have you every pwondered why there like that? There like that because the outfit that's doing the job probably under bid the job to get it and in order to make any money at all there cutting every corner than can and in doing so they end up with a crappy job.
Talking about bidding on some commercial accounts, well don't put the cart before the horse because a lot of those account that are being offered require your business to have a ton of insurance to even bid. If I were you I'd stay with Residential, your chances of getting work are better and if a commercial account comes along if you want to take it fine.
