Hi I want to move to Gib/La Linea Oct/Nov this year with my dog

Hi I just joined site tonight not quite sure still if I know what I am doing on here or if I am posting in right room???
Sorry if not - I will tell you what I am looking for and would appreciate any comments/signposting.
Thanks in advance!
I am a single man of 46 years and have no family left here in UK so thinking I would like to move to Gib. A good few years ago I spent some time in Gib and La Linea - just holiday.
I did realise that Gib is very small and cramped if you like.
IN A NUTSHELL what I was thinking of doing was later this year renting some (hopefully cheap) accommodation for up to 3 months to see if I could make some contacts/find part time work/secure long-term accommodation and hopefully full-time relocate to GIb.
I have a small Jack Russell dog who would come with me.
If you have read this then thank you.
If you can steer/signpost/give advice then thank you more.
Best wishes and thanks
Darren
