Right server to sign up with ...
 

Servers from brixly.uk and hostround.com are provided on sweet terms and I have to select the best one, so which way should I go?

Have a look at servers from time-tested companies: hostingsource.com and black.host.
Great hosts with fast servers and fast network connections. Very helpful and friendly support.

What are your current website management skills? What might you need help with?

Well-ballanced dedicated servers you can get from
1) GTHost.com
2) ZakServers.com
3) Hostdime.com
All that really matters is which web hosting is right for you.

Don't even bother looking anywhere else, hostingsource.com is who you need. They are exceedingly quick to respond to support issues, even from pre-sales stage. The attitude is always unflappable and friendly - just what you need - and the value-for-money on the packages is unbeatable.

I can recommend you try to compare rates, features, compatibility, performance, and reliability.

Nice web servers you'll find at QHoster.com - their experts will help you to choose the best option if you contact them directly and tell your specific requirements.
Good network uptime, speed and helpful techs.
