I'm in the US. I'm surprised you have such difficulty in finding a skate tech to perform blade alignment. It's an essential service. Have you asked coaches and competitive skaters at your rink who they go to?
You didn't mention what boots and blades you have; in particular, did you purchase your skates as a kit, with the blades pre-mounted? As you advance, you will purchase the boots and the blades separately. The blades have two types of mounting holes: elongated slots (two on each toe plate and two on each heel plate) and circular holes. When the blades are first mounted, screws are typically installed in only the elongated slots to form a so-called temporary mount. The slots allow you to move the blades in-or-out slightly to find the right position for your foot. In some cases, the slots do not allow enough adjustment. The tech then needs to plug the old holes, and drill new ones. Once the proper position has been found, additional screws are installed in the circular holes to form a so-called permanent mount.
In general, here are other considerations:
* If the blade has been ground with sufficiently uneven edges, you may have problems getting onto an outside edge. Good skate techs (and maybe some coaches) have special gauges to check the evenness of the edges.
* If the boot itself (sole or heel or both) is not level, the blade can be tilted. Good skate techs (and maybe some coaches) can inspect the boot to check. This can be corrected with shims.
* If the boot and blade are both OK, then your foot probably pronates.
(1) You can add an arch support or a heel wedge or both inside your boot to correct it.
(2) You can move the blade to the inside.
(3) You can shim the blade to raise the outside edge.
Try the corrections in the order listed: just (1) first; then (1) and (2) if needed; then (1), (2), and (3) if needed. Depends on how strongly your foot pronates. I need all three corrections on my skates (both feet). In certain cases, you also need to play around with the toe-to-heel alignment (which I needed to do on my left foot).
There's a lot of garbage on the web. But here's an informative article written by a sports podiatrist who specializes in problems with ice skating:
