I can add Mathematica graphs and illustrations at an extra charge. I can also produce graphs in Mathcad and Maxima if you require it.
I deliver in 3 days maximum and I can deliver the original LyX source file for an additional charge.
For longer documents please purchase additional gigs, contact me for discounts on larger orders. I will be happy to agree a price in your budget.
I will typeset a page of your maths and science document in LyX, a LaTeX editor and deliver in PDF
