It was curious see a website only for girls
You may be a bit wrong on it - these forums are
about girls, not just
for girls. As you may see, lots of educated and intelligent men are joining, too.

If someone can advice me jobs websites of Latvia
Most major I would mention:
cv.lvworkingday.lvvisidarbi.lvThe first one is the biggest one. And it also has almost full translation to English. Many job positions may be listed in English, too.
The other ones are mostly for local Latvian audience. You must know Latvian to get in.
Except those sites, I suppose, there is nothing spectacular. There is an ads board called
ss.lv but the jobs listed there are definitely not for foreigners.
Latvia has very low salaries comparing to EU, incl. UK and/or Ireland. And it also has too strong laws regarding Latvian language; basically, whatever profession you are related to, should be related to a certain Latvian category of knowing language.
I think, if you are up to "dirty" jobs at the initial level, for example, a loader or janitor, and if you know English well, you must start with English-oriented countries. You would have more chances there than in Latvia. Unfortunately.
Good luck.
