Not being legally trained your time cannot be "measured" as can a solicitor's time and thus you cannot claim costs in addition to your claim.
It is also possible that you may come undone on a technicality in your presentation to the courts.
For example, I have seen a case dismissed where a request for a court order was put before a court in general terms, not in the specific terms required, in relation to remedial works required to be carried out on a dwelling.
It didn't impress that the case had been prepared by a state solicitor no less, but it was expertly defended by a senior counsel and this and three other, similar cases went away.
What I'm saying is that even competent people err, and you are not legally trained.
If you have a mind you could let us know how you get on.
