Maybe you could come along to the London Vegan Festival on the 21st Aug. We're doing a stall & running a shoulder press contest for male & females (8kg for females max reps wins) you can enter the contest or just cheer on everyone else.
I've used hemp protein. The best one I've found in the UK is by good oil. It's grown in the UK & has slightly less carbs & more healthy fats than the Canadian stuff. I've only ever had the unflavoured as I hate flavours in protein (if I want flavour I'd add fruit).
I'd be interested in your low carb dietary ideas, could you put up an example day of eating at some time?
By the way if you are coming to the London Vegan Festival feel free to bring along some flyers for the stall & get yourself advertised as we often get a few people asking about finding vegan trainers when at these things, you never know you might even convince me to try out a vipr workout
