Yes, follow the suggestions about building your own - it’s easy to do and very satisfying to use your home made equipment.
The DK7ZB designs already recommended are good; I’ve also used the DL6WU design, for which there’s a calculator from VK5DJ at
These (DL6WU) do need a balun match, but it’s easy to make and the design software gives the details.
For 2m and 70cm antennas I have used 6mm aluminium tube for the reflector and directors, with a split piece tightly push fitted into plastic tube for a simple dipole driven element. You can drill 4mm holes through the plastic and aluminium, and use 4mm plugs to contact the dipole elements.
For a DL6WU folded dipole I’ve used 4mm brass rod, with the ends soldered to connector and balun.
All these tubes and rods are available in the UK from B and Q; search for “FFA Concept tube”. Maybe also available in your local similar stores.
For the boom, I use a single piece of 21.5mm plumbing waste pipe for a short boom; for longer booms in two or more pieces, the 21.5mm tube is a good sliding fit into 25mm electrical conduit tube. The elements are fitted through holes in the boom and held in place with rubber grommets. (It would be harder to do this for the DL6WU design, but I tend to use those for higher frequencies where the elements can be fixed - I strap an 8-ele DL6WU to the back of my rucsack!)
All good fun! Good luck with your antennas,
