mate it sounds like you now your limits,some lads who come straight from college may be good at skimmin and stuff but in the real world its different you really need to see it doneITS funny on here ive seen u guys say to so many before oh it takes years to learn properly and be ready, u cant rush it, here i am holding me hand up saying i dont feel ready quite yet and everyone saying go for it  ;D
i started this post to state that being in the process of learning and work drying up leaves me up the creek cause i dont feel i can fly solo and cant get on any walls to practice and get experience, without workin  :-/
day in day out for a few years,untill then there really only improvers,no offence to anyone,more power to you for trying to better yourselves.go the patching route with aggencies pick up a bit more trowel time,little domestics are sound,just dont bite off more than you can chew,keeping things clean can go a long way towards your rep,get stuck in mate we all have to start someware!
