What you refer to as a " shark " may well be someone like "me " or many of the guys on here, who are NOT novices and know exactly what they are doing.
This is why I continually try to inject some realism into pricing c/c work.
If you listen to those who tell you to always attempt to get the highest price you can, walk away from, price shoppers, etc, etc, while you have very little experience, knowledge, or ability to do a quality job, you will ;-
1. find it difficult to get enough work to just get off the ground
2. be unable to cash flow your business
3. find you are getting into situations you can't cope with
4. damage the credibility of the industry
Yes I said damage the credibility of the industry. Some imagine that the industry is enhanced simply by charging high prices for a service - which consumers can actually carry out themselves - and think this raises the value of the service.
Become your prospect and consider what you want done, how difficult / complex, is the operation, what credibility / track record, does this person have, who you are inviting into your home to carry out tasks, which, potentially, could be disasterous.
Do their proposed charges reflect true value, set against, your expectations / their claims.
How does their pricing compare to your hourly rate of pay, or to other services, you have previously used, or know of.
Do they appear knowledgable, capable, trustworthy, with a clean / tidy appearance.
Have they discussed how they will carry out the work, what they will use.
Have they stated their expected outcome. Is it similar to your expectations.
etc,
In other words.....................you are possibly competing with me, or one of the other, more experienced guys on here, who will easily answer all of the questions a prospect might have and by doing so, easily gain their confidence and if our price is more attractive, not because we're CHEAP, but because we KNOW WHAT TO DO..............WHAT TO USE..............HOW LONG IT WILL TAKE.
Please don't take all of this the wrong way, I am simply saying. If you are a novice in this, or any business and you get FREE advice................LOOK HARD AT WHAT OTHERS ARE SAYING and consider what will benefit you, not just today, from one job, but what could/ should result, from a job " well done "
Best wishes, whichever route you take !
