problem honing design ideas in very small area’

My patio area is small, my ideas BIG, i have learnt a lot through reading and shall chose two flower colours , pinks and whites and varients, plus various green vegetation. But as it stands i feel it will be too cluttered.where can i find a person who is knowledgeable who can just view it to give simple advice to hone down.i am severely disabled and new to gardening but its now a mega passion!
