I'd like to call my services "consulting". But consultants are often seen as freelancing development engineers. And developping is the one thing I do not want to do.

Additionally, freelancing developpers in my opinion always are a bad solution, even if your development team is drowned in problems. Maybe the freelancer solves your current problem and presents a working prototype. Then he or she is payed and he or she disappears.
And who is in charge afterwards, when problems arise in manufacturing, in quality control, in servicing?

So, better forget "consulting".

But I would like to be your coach, providing developmental know-how out of the field of opto-electronics. Providing this know-how to your engineers, who later on will accompany your product into manufacturing, quality control, service.

For this purpose, I can offer:
(a) Papers I have written about selected topics from the field of opto-electronics.
(b) Developmental assistance, discussing your current problems face-to-face in your lab.

The following prices and terms of payment apply for the aforementioned cases (a) and (b) respectively:

(a) Papers that are pre-published in this web site:
You can order the files of your choice to be delivered in one of the three following formats:
* Color print on DIN-A4-size paper   or
* in <*.htm> file format ("High Level Tagged Markup Language";
  for your web browser) on CD / on DVD   or
* in <*.doc> file format ("DOCument" file for Microsoft Word)
  on CD / on DVD.

The same price applies for all three formats:
For each file 2 Euros per kByte of html   plus   20 Euros per figure   rounded to full 5 Euros.
  The kByte-count and the figure-count of a paragraph (i.e. of a file) is noted in the index at the beginning of every essay. ...But you can also look it up directly in the table that follows below.
In this table, the paragraphs (as far as they are for sale) are listed together with their kByte-count and with their figure-count. Additionally, the price is listed per paragraph.

Do you consider ordering a complete essay? - Then the lower "complete essay price" (which is also to be found in the table) applies. In these cases, I will supply not only those "for sale" paragraphs, but the entire essay.
