Decision Time?

Don't know why but can't really sleep.. So decided to do some updates.. Someone from an enrichment company visited me on saturday, asking to rent out part of my space to them.. They are looking at 8 seats of my table for the moment and then add on as time comes. The rental that they have in mind and what I have in mind has quite a bit of difference.. If I take the offer, I'll have to do some minor alterations to the place AGAIN.. I'll need to add partitions to the area.. This is going to be another cost but then they are looking at renting it for 2 yrs basis, and the fact that this enrichment is for primary school children does give me an advantage in my crowd flow.. Hai.. Headache.. Let me think of it over sleep.. I'll need to reply them my final offer on tuesday..
