Sheep prices are very high at the moment but what I would do in your position is this.....
Go to market taking a knowledgable person with you and buy a couple of nice ewes with good quality lambs at foot. This may cost you around £120 or so for a ewe and twins.
They will need worming when you get them home and treating against fly strike. The ewes will give you a good fleece in June at shearing which you could send to someone like me for processing, the lambs will be ready for slaughter in October and you can fill your freezer, sell some to friends and have some lovely lambskin rugs made by sending them to a tannery such as Fenland at Bridgwater in Somerset. You can then sell the ewes in the breeding ewe section in market and if they are good quality and well turned out will make a good price.
Result.....grass is tidy, freezer is full, Xmas pressies for several people in lambskins and felt are done, the excercise has at very least broken even or even made quite a nice little profit to invest in some of the same next year and you can sit in front of the fire in January when us mugs are out feeding their sheep

Seriously this is a very good option.....and fairly easy to do, let me know if I can help
