Don't just look at the 'whole' scene and guess at the pricing.
Break it down.
1. How many models do you have ?
2. Large Upholstered furniture -- have any, .. all need to be modeled ? Estimate the hours for modeling / texturing
separately.
3. Cabinets / bookshelves/ tables etc.. have any ? ...etc.. Same as above. Make a chart with columns of
things you need and the time it'll take. For texturing, .. indicate the item and your guess at how long
it'll take.
4. Accessories (lamps / pots / candleholdeers etc..) Same as above --- keep modeling /texturing separate.
5. Plants / foliage ...
6. Modeling of the room.
Realistically figure out how many hours for the above --- modeling / texturing.
Make a chart with columns of
things you need and the time it'll take. For texturing, .. indicate the item and your guess at how long
it'll take.
____________
LIghting --
1. HDR / outdoor backplate ( do you have it / need to create it ? ... how long ?
2. setting interior lights - how long ?
____________
Test rendering
1. how long to check all your materials are good (test renders) ? I know this is hard, ..but guess, then overstimate by 30% -- write it down.
2. testing the lighting -- same deal -- write the guesstimate down. Six hours ? a day ? WHAT?
3. Final renders -- how many ? I'd guess at least 2 days to get a nice handful of good renders.
Don't write the full render hours down -- just note a the few hours it'll take to save files/start new renders
etc... Call it 7 paid hours.
Now --- get all that done. Do some math ...
Make a new chart, based on your hours and multiply an hourly rate. Do a range from x to y, ..eg...
total hours (H) x $20, $25, $30 etc..
Settle on a figure you think you and the client can handle .. Present it, indicate the hours requireed on the
proposal. If they accept, ..then YOU KNOW EXACTLY HOW MANY
HOURS YOU HAVE TO COMPLETE ANY GIVEN TASK. Stay on it, .. if you complete a task quicker then the estimate on your
chart, .. then your hourly rate just went up, .. if it takes too long, .. then you lose money and endanger
not meeting a deadline.
Don't tell the client your exact deadline --- give yourself some cushion.
If you don't do your homework here, .. then your just guessing and you'll lose, because human nature is to underestimate
everything. Ask anyone in this forum who's done professional work ...
Whatever your estimates of time on your chart are, .. you have to stick to it. Be a pro !
This is how it should be done -- the client is informed and you know what your actually making per hour. It provides a framework to work within ..
If the client didn't realize the effort / cost involved --- adios to them, unless your willing to work for a lesser dollar amount. Good luck W.
