Then it's simply a matter of arranging the client's content on each of the pages. Even at a rate
of £25/hour, meaning I can do the same for £50-70.
Do you have ANY experience? I mean, seriously, this is SO shallow.
- You are not 100% busy without a sales person running around getting all the work. Sadly that sales person will need to be - you know - PAID.
- You are not 100% busy even then. Sorry.
- Have you ever dealt with clients? Where do you get the idea they take your 2 hour work and are NOT going to add another 2-3 hours discussion, planning, presentation to that?
- And you really are sure people will like that? That is basically a business building websites the business do not need ("internet business card" style). The moment you get more in - you need more time. In your cheap area you compete with every student wannabe that undercuts you.
And - seriously... 25 an hour? What is that - Junior Web Developer? Do you have an idea what freelance people get paid? Sure you can work for that - which is not that much once you remove office costs, software costs (unless you steal it), reserves for bad times, reserves for sickness and holiday. Rule 1 when I am offering my services is that if I am not in the top 20% of the price range then I am not interested doing it, because I am underpaid.
25 pounds is per month, taken 20 days at 8 hours: 4000 pounds. This is a VERY good wage - somewhere in Poland, Ukraine etc. It is not exactly a decent freelancer rate in the UK. The last junior position offering I saw was in the 250+ range - and it was insultingly low. And again, you assume you will be busy 100% of the time - point is, you will not, and then you suddenly earn quite little. Basically so little it is better for you to be employed than to run that business.
You say in another answer:
I'm not sure what more a competitor could do for a client that needs a basic 5-page static
This is a quite little market of people that basically pay little for a service they do not really need. Your local bakery does not need a website, so when it gets one, that is such a thing. So, yes, you can make a niche there. It will not be a startup (scalability is not given, that is just a small business) and you will not really grow to larger client without a lot of effort - nothing to demonstrate.
Compare that with - if you have any decent skills - just skipping the "business" part and getting freelance jobs and you are a lot better doing the later.
Or you just forget all that running a businss and just work for 2-3 times that as decent freelancer ;)
