Advice needed on getting a job in UK/Ireland for an international applicant

Hello everyone, I am finishing undergraduate degree now and want to get a job in consulting or a similar function in a leading FMCG company in UK or Ireland in a year or so. My background: undergraduate in International business in the country's leading university but without impressive GPA, 5 months internship in Sales Department in a large telecom company but with no significant accomplishments, GMAT - 730, languages - fluent English and basic French. I would be grateful if you could advise me on how to enhance my resume to get such a job, because I am from Eastern Europe and I'm afraid that it will be a big drawback on my application due to the need of visa and low prestige of educational establishments.
