(UK based) What is a good conversion kit for a first build (30-35mph)?

Ive come acrross kirbebike kits and bafang kits, but thse are from a random assortment of youtube build guides. What would the community suggest I look at for a first build emtb that runs at 30-35 mph for a uk builder? (going the diy route to save money)

If you want something on a level with a factory made emtb then you’ll want mid drive. You’re still talking thousands.

I put a bafang bbshd on a trek hardtail. It cost £1500 to build and did 35+mph on the throttle but it was crap for anything other than smooth roads.
