Hello, guy from foggy London!  
 
 
Noone is your potential employer on the forum. The best advice I can give: go on to the job market & use all the possible ways to find a job. For beginning, surf the plenty of sites for seeking a job: 
www.gulf-news.com, 
www.careermideast.com, 
www.interfaceuae.com, 
www.jobs-me.com, jobs9.bayt.com etc. etc. Maybe you`ll be lucky to find it still in London. If come to look here, you`ll be limited in time with your visa. Anyway, you can extend it or maybe you are gonna buy some property?.. I can`t measure neither your needs or potentialities & possibilities but only can console you: Dubai is rich in opportunities. 
It`s a problem if you want to relocate to another country but don`t have anyone to rely upon. It`s a kind of the extreme I`ve experienced somehow too. My second advice to you: be informed, check twice all the information you get. Good luck again!
