If you can get yourself some well rotted farmyard manure - often given away- it would be good bulk for your soil and good for the pocket too. As you are new to the area maybe find your local allotments ask there for a good source...any allotment is always a good source of info for any new gardener. Sometimes they would have a shop or know of discount seeds etc locally.
Dig over your soil and incorporate the manure. You won't be growing in all your plot over the next couple of seasons so on the sections you are not using spread a good layer of manure - 15cm or so thick - across the top of the soil. The worms and weather will do the rest over the winter and it will help keep the weeds down too making it easier to work in the spring.
Don't do too much at a time and enjoy...you've made a great start!
