Seeking Independent Financial Advice

Hi,

What is the best way to seek out 'Independent Financial Advice' specifically for mortgages.

I'm considering a 'Let to Buy' approach to enable us to move house but need some financial advice on the viability.

I've 'googled' IFA's but I'm not getting far.
Are there any websites that list IFA's and what they specialize in?
I live in Manchester.

Thanks.
