I'd still avoid a foal, you will want to ride your horse - I thought the same thing when I got an unbroke 7 year old, thinking "I can wait till she's trained" I was on her back in a month. Luckily she tolerated me up there xD
Foals are SO complicated and sure asking for help is great - but can you afford help? Can you afford the extensive vet care you're going to need for a foal? Do you know the proper diet and nutrition for a growing foal? I recommend, if you're serious about getting a foal spending time working at a breeding farm. A LONG time. Foals are work - not much fun. They have the attention span of a gnat and need constant work and rework and you can never slip up you aren't given the wiggle room forgiveness an adult horse will offer you.
If you really want a project get a green broke (as in, has been sat on but not fully trained) draft cross. I see no reason why you need to stick to pure breeds, draft crosses are Amazing animals! Get a shire QH cross, lots exist! Most of them carry the best qualities of each parent, soft and agile like a QH, strong and pretty like a shire. Stick with something you can honestly handle. Draft horses are BIG and they know it. If you really want a draft find a draft horse rescue to volunteer at to learn how to really handle them. Get experience with each type of animal before you pick. That way you make an educated opinion.
