Join your local gardening club/horticultural society... lovely people, knowledgeable about what does well locally, loads of help, advice and encouragement.
You may wish to employ someone, if your garden is large, half a day a week may be enough. Depends on how fit you are, finances, time etc., but take advice on who.
I have a large garden and employ a "slash and burn" merchant as I call him, who will tackle anything with gusto, and someone else who is RHS trained and totally understands plants and when to do things. I still do loads to, and between us we hack it.
