Development of landscape design of the garden plot

We need a specialist in landscape design. It is required to develop a landscape design of a garden plot of 8-10 acres. The plot is located in an old garden partnership in the Moscow region. The existing trees must be considered. I want to get a site that requires minimal care (within reasonable limits). From fruit trees it is necessary to place: pear, plum (yellow and blue), cherry, from bushes: currants (black 3 bushes, red 1 bush, white 1 bush), gooseberry 2 bushes, possibly something else. Place for small beds under greens, vegetables, strawberries pyramids / barrels. A couple of three flower beds.
Along the outer perimeter of the site plan a kind of hedge, preferably from evergreen plants.
If possible, that ornamental plants are unpretentious to care and watering. If it is possible to spread their flowering period so that they bloom at different times.
You also need a hammock for adults, a swing for children and adults, a slide, a small sandbox (you can then turn into a flower bed) as there are children 9 and 2 years old.
The barbecue area, the kebabs near the house. The slack in front of the house.
Also, of course, you need to take into account the presence of buildings, paths and communications.
