We already have staff in place, and we are a large enough company with over 150 contracts of similar or larger size in place already, taking on this type of contract would be a normal days work for us, we have the systems, process and labour to accommodate without affecting my other business. My advise was primarily regarding how to price and my observation is that this is not normal business for Clean-Master
I had assumed that Clean-Master had little or no experience of quoting for this size of business and he wanted advise. I pointed out that there would be a lot of interest and he could end up wasting his time and effort, unless he already has a relationship with the client, in which case he should find out how he can add value to his proposition, thereby increasing his price to the client.
I would suggest at this stage reviewing the business plan and delivering against this plan, if this is outside of the business capability leave it to others and focus on his own business plan, after all I would not want to become to reliable on one large client and therefore put at risk all my other happy customers.
Typically this type of client will request a minimum of 3 quotes, (often it is 10 to 15 quotes, they measure stability, delivery, value, flexibility management, relationships, reporting, and then again they look at value, then they should look for similar business references.
My advise is to grow the business sensibly, stick to your business plan, you will have plenty of staff relying on you to pay their wages, do not overtrade it will kill the business quicker than poor service as anyone managing tight cash flow will confirm.
PS it's only my opinion, and I have jobs that pay less than £8.50 per hour and some that pay £45 per hour, it is about balance and value
