Hi, thank you for your question. I have listed below some parts that I think will work for you. I have suggested two possible frames that you could use as there are advantages and disadvantages to both. The U580 frame is great; it's light and will meet your specifications but due to its light weight, there is a limitation on space for extra equipment. You will therefore maybe have to think about adding an extra plate if you wanted extra equipment. I have then recommended the FQ700 frame also as this is a bigger frame, and so should be fine for space, but it is heavier and more expensive.
The total weight of all of this equipment is approximately 2.1Kg (with the U580) and the max take-off weight that these motors/props/battery provide is 3.6-4Kg so this should leave plenty of extra weight.
We also do not currently stock the 9000mah battery that I have suggested but Unmanned Tech will soon be stocking these batteries. Alternatively, you can find an equivalent battery (4S, low discharge rate at around 25C with weight at approx 800g) for now.
The total price of this equipment is £533.27 with the U580 frame and £563.28 with the FQ700 frame and so meets your desired budget
Please let me know if you have any questions.
