Digital BW, The Print

Hi, I'm Sorry for my question but here (Central America) we are a cuople centuries back in tecnologies and information about digital printing. we are using a wet process to do a 2x2" identification photo with a white or gray background and the people usualy dress black clothes. we are losing time and benefits of digital cameras.
what I plan to do is, get a epson r280 and Inkpress fine art matte paper to emulate a darkroom photo.
have to make a 100 photos a month and December goes to 500

Questions:
1. Is this paper textured like old wet paper
2. can use another no expensive paper
3. have to buy a continuos flow to printer (plan to do BO printing)
4. if I use a MIS Inks carbon cold tone have to use a six inks. or can use a ebonni black only.

I already make some test with canon ip1800 (regular ink) and epson matte finish inkjet paper, that looks good, but is not what I need. Can make any decision because can see results. first have to buy in US over internet, expend money for things I dont kown gone to work. have already over 2 months seek for info and cant find the information to make a decision. 

please, please, help me
