Learn how to market...
Remember, most people loose money in business because they think that just having a skill that they are good at is enough to make them rich. You not only need to research what it is you would like to do, but more importantly you need to research HOW TO MARKET!
If your friend has $500 k then I would recommend him purchasing Jay Abraham’s “Mastermind Marketing Program” not the one listed on his site but the 2002 program. It will run $5,000, but is well worth the money.
It will teach you how to look at your business from “outside the box” and see all of the free or low cost marketing avenues you can take to get your business off the ground.
To use an example, and hopefully help two people with one post.
If I were to start a landscaping business, I would do the usual marketing that all successful landscape businesses follow, but I would also talk to every electrician, plumber, carpet layer, construction company (that builds new homes and renovates), any rental place that rents lawn care equipment, etc. to set up a referral system. For every referral that they send my way I would pay them either a percentage of the sale or an upfront fee.
Also, what ever you do, set up a database to track your numbers, and keep all your important client and prospect data!
Basically, KNOW THY NUMBERS!
Just because something costs you $1,000 and you only make $500 from spending that $1000 does not mean that it is a bad investment. If you can get those clients to come back four more times in the lifetime of the client you will have made $2000 for every $1,000 you spend.
Sorry this is getting a little long, but I really love this stuff. If I can help you in any other way let me know.
Peace,
