Would like 2 fairly smallish gardens sorting

We would like 2 smallish gardens de-weeding (and weed killer putting down (see must haves list) please be aware that there are sharp thorns and nettles in the weeds) One of the gardens needs levelling (so it's all about the same level (it's very uneven at the moment) We would like the small trees cutting down (see must haves list) not the big one! Once the garden is level (please be aware that there are some larger stones/small bricks in the soil) We can despose of these but not any of the garden waste like soil or weeds) We would like weed blocking stuff putting down (we have this but it's a cheap one and I'm not sure if the price makes a difference on the quality and whether it will let weeds through in the future (if this is the case please could you bring some if you have any available) and then finally we would like bark putting over the whole of both of the gardens (we have this already) I will try to help where possible but I do have mobility issues so may have to keep having breaks to allow the pain to ease off I should be able to add pictures of the gardens soon if that will help Thank you for looking and hopefully see you soon
