To be honest there are millions of extract recipes on the web and you can buy the ingredients separately for them. The homebrew company sells 1.5L cans of extract for £4.95. And 3kg of DME for £14. Get some crystal, chocolate, roast barley etc and some hops and off you go.
You can also convert a lot of AG recipes pretty easily. For example found this recipe for a 3.5% ABV mild (19 Litres):
http://www.seriouseats.com/recipes/...-ale-for-intermediate-homebrewers-recipe.html
4.75 pounds Maris Otter malt, crushed
0.6 pounds Crystal 40L malt, crushed
0.3 pounds Crystal 120L malt, crushed
0.15 pounds chocolate malt, crushed
0.5 ounces Northern Brewer hops - 60 minutes
1 package liquid English Ale Yeast (Whitelabs WLP002 or Wyeast 1968)
Crystal and chocolate can both be steeped, so extract version just needs extract instead of Maris Otter.
4.75 pounds = 2.15kg grain
Dry Malt - Multiply by 0.6 = 1.3kg DME
Liquid malt - Multiply by 0.7 = 1.5kg LME
You could use other hops - Northdown or Challenger for example. They are really just to provide some bitterness.
The 40L and 120L crystal are different colours measured in Lovibond. In the UK most grain is described in EBC colour units, which are roughly double - so you want crystal around 80ish EBC and 240ish EBC. Don't worry about differences, 20 EBC won't make much difference.
