i started my business a week before christmas. or i tried too. my younger brothr passed away the same week putting things on hold a bit. but you can set yourself up anytime because the work wont start coming right away anyway. id get your equipment and your business insurance and all that set up before you start advertising. use your equipment at home and do some familiy and friends home to get a feel for things before hitting your territory.
whatever you buy save some money for marketing. again it will take time to set up ads and whatever marketing you choose to do. by the time spring rolls around you should be starting to book jobs and be prepared for them.
good luck and have fun.
That is good advise.
Also, it depends on your financial situation.
Do you need to start making money right away, or do you have some financial cushioning?
Yes, a truck mount is much better and will allow you to do a better job in less time. However, a portable will be less of an investment, especially if you already have a vehicle that you can use. However, if you take the time, a portable will do a great job.
Also, if you buy a portable and live in an area with buildings higher than 3/4 floors, it will not be a wasted investment, as you will still need it, even if you have a truck mount. If you buy a portable, get a good one, with two high flow three stage vacuums and a 500 psi pump (unless you also want to do tile, higher psi if you do)- these new vacuums are awesome.
Don't expect to make a lot of money quickly. For most, it does not work that way.
And I'd double emphasize what people said about the importance of marketing.
Good equipment.
Knowledge and pride in your work are very important but worthless, if you can't find new clients and retain the ones you have.
Good luck.
