I am a 29 years old male and I would like to start a new life in the UK (preferably in a big city if not in London).
I have nothing to put on my CV mostly because I can not validate anything from my past experience..
I have strong IT knowledge and worked in various small business IT positions from assembling computers to setting up small to medium networks for other businesses, providing technical support etc. I have a very small engineering background(1 year lessons + 6 months practice in a cargo ship as a junior engineer).
These are the more "official" jobs I have done but I was not officially registered as an employee (for tax evasion purposes I assume) and that is why I can not prove any of that in my CV.
I also have done a variety of other jobs such as door to door sales, call center operator, waiter etc my education consist of a high-school diploma and some semesters in the field of applied mathematics as an undergraduate student and I also have some basic coding skills in VB,C,Java and python and a comprehensive knowledge of MS office -as does everybody I guess

But as I said I am 29 years old I have two hands two legs a sane and witty brain (I hope) and the will to work hard and make a living.
My 1st year goals are these:
Find at least one job (or e.g two part time jobs or a full time and maybe some part time etc) and stick to it.
Be able to sustain my self (pay for decent speed internet, electricity and other bills as well as normal food that wont make me sick or fat -like cheap frozen pizzas and cheetos- )
Be able to live in a neighborhood where I could stroll around day or night without being afraid that a gang of chads would put a knife in my bag just because they dont liked my face or to steal my cheap phone etc.
Be able to live in an apartment (preferably alone but I understand that this might be expensive so roommates are ok) with basic hygiene where I can sleep without having cockroaches or mice walking over me and having basic privacy where I sleep and for the bathroom.
Be able to pay for lessons or books to get some IT certifications such as cisco CCNA.
Be able to buy a second pair of trousers if my current one needs to be thrown away or to buy a basic TV and other non luxury essential accessories or pay for lets say piano lessons to relief the stress of being an immigrant and working hard to survive..
My 2nd year goals include my 1st year goals but also
Be able to pay for getting an advanced certificate in English such as IELTS or TOEFL
Be able to enroll to a university (I have the grades) and hopefully live in a dorm (else the living conditions of 1st year goals apply) -Also preferably getting a student loan to enroll in the best University I probably could.
The problem is that I know 0 stuff regarding how it is to live in the UK so I need advice on how to start like:
Which cities are more suitable for meeting my goals (in terms of having more entry level jobs compared to others and good living conditions)?
Which regions inside those cities should I look for finding an apartment?
What is the minimum necessary spending money I should have when coming here? (the less the better)
what listings should I avoid ?
Are there any scams I should be aware off? Any dodge stuff I should know?
Were would you look for jobs if you were in my shoes? Any other advice and tips?
Generally I would like to imagine yourself in my situation and think of what would be best to do and what would be best to avoid and generally share with me some of your streetsmarts.
For example there is this business company weblink removed by moderator which for some reason asks for Greeks to come and get trained in cooking and taking care of elderly people and get paid for that.
But upon googling the brand further I saw mixed reviews were quite a lot of them were plain out negative mentioning that the pay is bad and that they have to work many hours and pay for taxis in order to get to the places they need which makes working there expensive etc.
So I am worried that if may find a job that will deplete my resources and finally get scammed or not being able to get by and that terrifies me ...
I thank you all in advance
