i can recommend airwolf's T1000 (allegedly) cockpit for about 100 eur, on AliX. I bought 6, very happy. afaik they only one 1 such model on alix, you cant miss it.
dont buy airwolf frames though.
for wheels, agree w Ludo. you can message Peter from Xiamen carbon speed on whatsapp and ask him what he can do with your budget, it's enough for a really nice set of wheels with T800, good steel spokes (you can ask for pillar wing 20 if budget allows) and house hubs. Dont get the 100% T700 option, wont be as nice, it's worth spending a little bit extra (really not much).
