I recently paid for a load development. I am a reloader but more of a "follow the recipe" type reloader, skill wise. I admit it. I also don't have the time, range facilities, or expertise to do it myself so I sent my rifle to Steve Davis who is the owner of Hammer Bullets. 3 weeks later he sent me back my rifle and 200 loaded rounds and it costs me right around $1,000 bucks.
My rifle is a 7mmRemMag. It shoots his 155gr Hammer Hunters into a cloverleaf at 200 yards with a MV of 3,260fps.
I GUESS that if I had the time, range facilities and patience I could have developed a good load myself but I don't think that it would have been as perfect as what Steve wound up with because it is a maximum load that is also deadly accurate. I don't know enough to play with pressure signs, seating depth, and charges to the degree that a guy like Steve or some of you guys here can, so I was happy to pay for that expertise and know that I have the best load possible for my rifle.
Sorry OP, I diverged from your question a bit...my answer is $1,000 for the reasons stated
