**Need someone to build an outdoor A-frame tire swing

I'm looking to build an A frame (although other ideas are welcome) outdoor tire swing. The smaller ones for sale online (5.5ft. high) are not tall enough for my 2 special needs sons who are 9 and 11. (and quite tall) so again, open to suggestions, but thinking about 7.5 ft. tall pressure treated wood tire swing. Please send me a price so we can discuss 🙂
