Laser Engraver for a project - i need your help!

[thodoris]

Hello to everyone from Greece!
First, i would like to say that i have no idea about laser engraver machines at all.
I am writing about a botanical park project that we are working on a Greek island. For the needs of the park we have to create small wooden signs (some hundreds) with mostly texts ( plant names - information ) and probably some simple graphics.
I am thinking to order a cheap Chinese laser engraver and try to create the signs i need. I did a quick search and i came up with the next machines:

My budget is 200$ to 300$.
I would like to hear your opinions, do you think i will be able to create the signs ( i can engrave the signs one by one -there is no rush) ?
and your opinion about the above machines ( are 2500 MW enough ? ), do you have any similar model to recommend me?
Thank you,
Thodoris

You only needs small wooden signs for park don't need a laser machine , that is not a wise long-term strategy.
In my opinions,you can find factory processing.
Firstly,with a limited budget the chose is handicapped in its operation.Price differences are used as a proxy for differences in quality.I check you chosen，the machine only use in DIY or household.The machine ability in engrave could not come up to the requirement.
Secondly, little knowledge on laser machine
If you needs processing I can introduced to you .

Hello, thank you for your answers!
The reason i prefer to have my own machine rather than ordering the signs is that i can add / edit a sign whenever i want easily.
Any other opinion? why do you think that i won't be able to do what i want with these engravers?
