you really need some professional advice.
you will need to be police checked if you are going to work with young or vulnerable people.
you should ask your council if they have a funding officer and set up a meeting with them and ask what is available - at the very least most councils have a "community chest" of a grand that can help get the ball rolling.
once youhave your grand you can look for ANOTHER building to hold your activities - if there is one in the area - you will be seen as a god botherer - mind bending happy clappy christian type who wants to brain wash everyone. besides if you have any muslim members of your community its not inclusive to hold activities in a church and this should be remembered when you WILL be telling the council that you are including all sections of the community
re: the residents association - have they sett themselves up - are they all homeowners or tenants or mixed? this is important becuase if they are tenants or leaseholders of the council or HA then there may be a resorce in their TP officer.
The council will have a Tenant Participation officer - if you have council properties nt he area set up a meeting with them again asking about funding.
you should set up a community group - get people involved get a constitution ( set of rules the tp officer should have a "modle constitution" you can amend) call your self anything you want - make sure you have the backing of the community - ask everyone to a meeting have elestions for a chair secretary and so on then go to the bank or building society and ask them about setting up an account for your constituted group - they will require the chair person and the treasurer which you have elected and a copy of the constitution - this should be straight forward
once you have a bank account you can go seek funding - without this it is difficult to get funding becuase you cant even get hold of the community chest miney without begging the council to pay invoices for you and to be honest they most probably cant be arsed.
you need a goof filing system kept by your secretary and all reciepts to be kept safely
all of you should get police checked if you are working with children
you can then apply for other types of funding such as
The Big Lottery Fund
Awards for all
Future BUilders
LLoys TSb
Esmee Fairburn Trust
Cooperative do a small one
some other banks may do some
and the funding officer will be able to help you
wyou will need to demonstrate need so consider doing a survey of the area asking what people would like to see improved
if considering diong up cars - remember there will be shit loads - absolutley shit sloads of healtha nd safety stuff to consider - you cant just get a banger and teach some kids
you will need permission from the council for somewhere to hold the car in safe keeping - they will prolly want to charge you
you may need the consent of the residents in the surrounding area as noise from kids , cars being started etc if a major factor.
you need to find some good community projects not too far from you - any one of them worth their weight will be only too happy to set aside an hour or so and give you pointers
remember when demonstrating need in the applications the council are bound to have a shit load of stats you can steal.
hope that helps
