Landscape 3d drawing needed

Hi there, im looking for someone to draw up a concept i have for our backyard design. Im struggling to visualise all the elements ive chosen and need to see it drawn up. Would need a quick turnaround time and if we work well together i will definitely be needing more help down the line as we renovate the house! I'll attach a very rough drawing i made but believe me its rough!! We would need to chat over whatsapp or skype so i can explain more of the design or vision. I will also attach a picture pf the garden in its current state so you can get an idea of the space. I have a landscaper so can ask him for the measurements of need be. I can also send pictures of different elements like the stairs i want, the pebbles, colour of walls etc. Hope this all makes sense and look forward to working woth someone on this!
