Prioritising is key then, as obelixx says. I'd start with a nice little sheltered, private area near the house. If you do that first it keeps you motivated when you look out the window on the days when you feel a bit jaded. Simple screens of trellis on posts for climbers, and shrubs like your Fatsia will quickly give you that. Phormiums will fit into that scheme and you can add some taller things behind, or put them in large pots with smaller things in front of them. They're easy to find almost anywhere and a good sized specimen can be divided to give more plants. Gravel is a cheap way of creating an area to sit and have a cuppa while you contemplate your estate!
A really good focal point somewhere in the middle of the garden will take the focus away from the openness at the end when you take away your trees, and help disguise the greenhouse and the working areas of the plot. That can be almost anything from a tiered island bed to a statue or specimen shrub, or even a row of tallish plants to create a screen that will help divide the space up for the areas you want to plant.
Once all the bulbs have appeared, mark them so that you can lift them when they've died back and you can relocate them when you have the right places for them. You can stick them in pots near the house and that will also be a great visual for the end of next winter into spring. It's always good to have something cheery to look at during the dreary winter months when we're all longing for warmer days
