Small claims is up to £5k. Beyond that, you will be allocated to the fast-track or multi-track which are more expensive and more complex (really need a lawyer).
Starbuckone made several mistakes - the first being using a solicitor for Small Claims, you can never recover solicitors fees in small claims (but the flip side of that is you can't be made to pay them for your opponent if you loose).
Secondly, yes you do have to enforce the order yourself - and if the other party has no money, you won't get it (blood - stone - etc). The options available to you (and probably still available to Starbuckone) include an attachment of earnings order, a charge on his house (if he has one), freezing his bank account or sending the bailiffs in.
