No problem at all.
At the risk of teaching my granny to suck eggs.
Remember you MUST make regular income, don't rely on the odd person who may need an emergency job doing over night, this will make you bankrupt very quickly. You need to get regular bread and butter work in, which will involve you knocking on many company doors, and letting them know you exist and you have a niche service.
The best way to look at it for me, is if i was a bank manager, and you came in to ask for a loan based on the business, what turnover type of work on the books would you need to have, to give me the confidence that in 5yrs time, you will still be there paying the payments.
Something i didn't add to the last post, as it was getting to long, is become preferred suppliers to large organisations. One of my closest friends has started up a specialist crane hire company, he has spent the past 18 months traveling up and down the country, introducing himself to local councils and transport organisations, letting them know that he exists and jumping through any hoops needed to become preferred suppliers... he is now making great money and the company is booming.
What a lot of small businesses don't realise is how to get the good contracts, from large organisations and public companies, you MUST be a preferred supplier. So the only way to do that, is literally call the company and ask them "How do i become one of your preferred suppliers". They will tell you how to do it, send out any info packs and application forms, and then add you to their list once you have filled in all the paper work.
The paper work can be very lengthy, it will ask for your health and safety, sickness, disability, maternity, risk assessment, etc policies. Even if your a sole trader, with only you working there, they ask for these, it feels like a waste of time, and you almost want to write jokes in them about how you will contact yourself to notify of your sickness, but they are just hoops to jump through. Most organisations only ask you once to fill it in, and once you have done it 2 or 3 times, they get much easier as you can start copying and pasting from other forms. Your weekends will be full of these forms... they are great fun lol.
What this means is when a council worker is gritting the road, and his brakes freeze up due to the cold on a dark, horrible night at 11pm, or a traffic management company van won't start at 4am in the yard, they can only call preferred suppliers for help without the permission of the finance management, as you have already been screened, checked and accepted. Most contract hire companies will not opt for the maintenance of the vehicle in the contract to save money, and many vans and light commercial are not under manufacturers warranty, so need your help.
You will almost always need to be VAT registered, and need to give 3 references etc. My wife is the head of the finance dept for one of the the local uni's where we live, which means i get to know in detail how this process works. For example in the northeast, all the north east unis are linked together, and use
NEUPG (North East UNiversity Purchasing Group), so once you are part of one uni, you're part of them all. You will also be expected to give a good rate and service above and beyond your usual.
If your not on their list, you cannot apply for tenders/jobs, no member of staff in any university can contact you or ask you to do any work, because no purchase order can be drawn up by the finance teams. It would be unfair for the people on their list, if you have spent all that time becoming a preferred supplier and then they just call anybody from the Yellow Pages (does anybody still use them?).
These are the types of people you need to get in with for your type of company that has a niche, as servicing a Vauxhall Corsa for Joe Blogs in the street, will never sustain the company for long and you will struggle like many other small companies with cash flow... and then blame a media manufactured non existed recession

Sorry if any of that is patronising, as it was not meant to be.
