OK, I really dislike reading comments like Sophie's above and I do not find that comments like that do anything but discourage conversation and learning. After all, learning is why this forum exists at all. Ignorant comments like that run people out of forums like this, prevent valuable conversations that help others out, and push people towards less informed decisions.

irol96 came here to ask a question about potential options, not for someone to say "It just shows that you have no understanding of doing any of this and should not be DIYing anything.". Obviously irol96 doesn't have enough understanding of what he/she is doing, otherwise this post wouldn't exist. Saying that someone should not be DIYing anything is overly harsh for one comment is overreacting. Not to mention that irol96 said "would a professional be able to...", not "could I DIY...".

@irol96, it is extremely difficult/near impossible to fill that large hole in your cabinet doors, sand it smooth, attach a new hinge to the routed side and then paint the cabinets while keeping them looking good. I don't see you coming out ahead financially doing that vs. having new doors made (be sure to change out the traditional looking trim/molding at the same time) or replacing the cabinets all together with cabinets that are your style/color. From reading your other thread and this one, you are very interested in painting the cabinets. If you want them painted, get a quote and decide if you want them painted based on that quote vs. getting them replaced with shaker style painted cabinets. I am partial to stained wood and love your kitchen, but if you don't fix it. It's your kitchen. If you don't like your 48" range (I'm drooling over that), get some quotes together to replace the cabinets and range at one time, go with painted a lighter color if that's what you want, and save your money until you have enough funds to make it happen. If that range works well, you won't have issues selling that and covering some of the costs. You may be able to get up to $500 out of it depending on condition and market. Most people buying that size of processional model will want brand new one, so you would never come close to getting back the amount of money one of those cost.

Another suggestion that I have for you is to change your light bulbs in the kitchen to whiter light. Every inspiration pic that you have shows a kitchen with white light bulbs (~4000K color) instead of your kitchen which looks more yellowish/warm white (~2500K). That change may make it feel much lighter and less dungeon-like while you save up the money to do what you really want.
