Why not get a local eBike technician / engineer who’s competent to do the work. That way you can discuss your requirements and options with them. So you get want you want, rather than keep spending money on items that you don’t know will work.

They're all much of a muchness. The bigger they are, the more robust they are, but they're heavier too. The Q128H (up to 7 speed) or Q128C (8 spd or more) are very good, though not legal, but you have to buy them from China (BMDBattery, Topbikekit, Greenbikekit). Without special requirements, any one will work for you, so buy whichever one you want.

One thing you do need to keep an eye on is the speed. 201 rpm is 15 mph, 260 rpm is 20 mph and 328 rpm is 25 mph. with a 36v 15A battery and controller, there's no point in going over 260 rpm because you won't have enough power for the motor to run efficiently.

You will lucky to find one who knows much about hub motor fitting, most of the good fitters are the likes of some of us on the forum. We do it for fun and not business.
If near Southend then Woosh would help.
