As stated, yes, it is an excellent idea to condense a circuit into the smallest possible size thus saving on board physical dimensions, 
  however ....in doing so, there are strict "electronic" rules that govern the passage of electrons along a particular  circuit board track 
  which may induce cross-talk "noise" from one circuit to another, please be very aware of these constraints and there are trade-offs in 
  any circuit board layout or design, speed and noise immunity are the most sought after features requiring "ground planes" to shield or 
  rather contain and reduce "cross talk" or high frequency "parasitic" oscillations from one track through a circuit board track to another.

 Labour rates    Repairs and modifications. . . AUD.$110.00 per hour ($1.8333/min)...Plus GST.
                    ( calculated as time taken in hours and minutes )

  Call-Out rates  (we come to you)   Repairs and modifications. . . AUD$110.00 per hour ($1.8333/min)....Plus GST.
  ( Calculated as time taken in hours and minutes plus $1.20 / Km there and return to base )

 
  Please note: For repair work, it is advisable to acquire a correct circuit diagram prior to delivery
  of your goods or equipment to be serviced and repaired. If one is not supplied, then we will need to
  " reverse engineer " the circuit and trace it out fully establishing a correct operational drawing.

            Labour rates design work   Prototyping...AUD$150.00 per hour ( $2.50/Min )...Plus GST.
( time taken calculated in months,  weeks, days,  hours and/or minutes depending on complexity )

 Please Note: Labour rates do not include any materials or components nor do they include GST.

 All parts and materials used are in addition to time spent on the client's behalf to get a project to fruition.

  Please be aware, we are not a "results only company", that is to state as in " only " being paid " only " if the 
  result is goods or equipment works.  We accept  " your goods "  for repair or service in good faith, however if it is found 
  at some stage during the repair(s) that the said item(s) for repair or service are not going result in a  positive working 
  outcome, either due to the age of item(s) or component(s) that are " still now " available in stock, we will advise you of 
  the costs so far in arriving at this conclusion. There are no "Free lunches" .  All company time is accountable for.
  This is only fair as where you work, you would not like to be NOT PAID as a result of a project or job not working out right 
  and your boss telling you, "tough luck mate...it did not work so no pay for the hours wasted on trying to get it going".

  We require payment for company time spent on your behalf working on your goods or equipment irrespective of the final 
  results that the item(s) in question are working. We strive for perfection in servicing and repairs, however there are 
  times where component tolerances change over the years, thus often resulting in undesirable parasitics etcetera.
