You can surely build up your own school website, as nowadays, GoDaddy and other sites are having in-built apps that help you design one. As you said you are not aware of how to get the domain and hosting, but this information you can get online. There are many "How to..." articles you will find to setup your website after buying hosting and domain. The usual companies from where most Indian bloggers buy their domains is GoDaddy or BigRock. When you go to buy their services, make sure you search for coupons codes. Usually, for the first year, the prices are quite cheap. Only later on, you will have to pay full price.

The other thing coming in your way is the technicalities. That will restrict the functionalities of your website and won't give you the desired effect for the way in which you want it. For example, setting up, emails, online forms, loading content updates will pose a problem for you.

If you think the price the website developers are asking is too high, let me enlighten you, that you can get it done in much cheaper rates - in as good rates as 3500 INR and even below. You can even post your requirement on Facebook groups and state your budget if you have any. There you won't have to spend a penny to get in touch with several website designers, and you can choose the one which suits your budget. You can also look at some Freelancer websites for hiring people.

Designing a website requires the knowledge of some software tools like HTML, Dreamweaver etc and it is also an imaginative work as how to keep your different elements on the web page so that the surfer has a convenient surfing in your site. The menu and buttons for going deeper into the webpage are to be conspicuously and distinguishably placed on the home page.

The easiest way to create a website is go to some of the sites in the internet which help in selecting the tailor-made web templates and designs to choose from.

Some of these sites provide 1 year free domain name ( with .com, .in, .org and other extensions ) also which is renewal for about Rs 2000 - 3000/ year afterwards.

The advantage of using these sites for website building is that one need not to know the programming languages or other tools as the site will do it for you in a step by step procedure.

You can have a better deal if you visit some such sites and compare their facilities etc. Hiring a computer professional for the task will be a costly affair though that will be a smooth ride for you.

Its nice that you want to prepare a site. But I think you can prepare on your own if you have knowledge on computer as you mentioned in query. Before creating a site you need to decide two things.
1) Whether you want a independent site named on your school and even if you don't think if its costly. Then you can hire a developer for a handsome site.
2) Other wise you can create a site by blogging in e blogger. Its very simple for your basic school advertising site. This is actually handled by google. You can create links within the page. But you will not have a site instead blog, where you can advertise that blog link in different ad sites for your publicity of school. If you need more details you can just login to your gmail and just go to eblogger at right hand which represents like E with orange background. For detail information regarding this you can just check in you tube for e blogging in blogger.
I think this will help you initially for your school. Even it works out at no cost.
