Nearly all of the ones in dho gates are atrocious. I would not recommend any of them, especially the ones that say “99999 skillchain 2 GEO”. Good luck getting your full money’s with in a reasonable time. I gambled once and bought a service because it was for red mage and I was regrettable lazy to hit 1200. Took 3 days to finally get them to invite me back to the group to finish my points (I actually finesse them for about 200 extra). It literally took them about 9 full hours to get 350~ points. Their bots are arguably not even better than just killing with trusts, it’s very bad service from some of them. You’re rolling the dice hoping to get a good one.
If you must buy, do it from someone reputable in outer rakaznar. You’ll generally get all of your points in only a short time. But if you want some real advice, just do it yourself and save your money. It’s campaign time and it wouldn’t take you more than one week to master a job from scratch if you did about 2 hours of cp/day. That 10m could go towards something better imo
