You've posted your question just one day after the UK's new immigration system came into operation. It's a lot easier to understand but, for many people, harder to get in. See here:

(For further information, click the 'Applying under Tier 1' link, at the top right).
Your problem in getting in might lie with the areas in which you're qualified. Only 'shortage skills' will get you sufficient points for entry. Since the demise of the USSR, many former 'eastern bloc' countries have now joined the European Union. Apart from a few temporary transitional arrangements, any EU citizen has the right to live and work in any EU state. That means that, for example, the UK has been almost swamped by plumbers, builders and electricians from Poland, Hungary, Lithuania and other new EU countries. Employers will only be allowed to sponsor someone from outside the EU if there are no EU citizens available for employment which, given the vast numbers of EU workers who're already here, would seem to be unlikely in your case.
Age discrimination is illegal in the UK but it can be hard to prove and it certainly still occurs (even though there have been some improvements since the legislation came into operation).
