Can anybody tell me what will be the recommended toll/software for a beginner to design a webpage which contains input boxes for numbers, tables which will be populated as result of calculations with complicated algebraic formulas and real time graphics as for example similar as in the next webpages?:

In my situation the curve on the graphic is already known, on logarithm scale, and 2 cursors, one vertical and one horizontal which have to move along the curve from graphic after result of calculation.

I was thinking that maybe Adobe Dreamweaver can do the job.

Do you have any other suggestions, maybe simpler? Adobe Muse seems too simple, or?

If I hire a web page designer, how long time is estimated for such page to be done? And how much would that cost?

P.S. I have done an VBA application in Excel to do the job and now I would like to make it as webpage.
