I would question your business proposal, firstly you have just moved to larger premises, so I am going to break the 8th deadly sin and assume, I am assuming you have an increased rent, along with increased Council Tax.
Surely your first priority is increasing your profitability with your current equipment, this puts you in the position of then looking to finance any further Capital investment, from your profits.
If it is large scale printing equipment, you are into tens of thousands at least, if not £Millions.
Alternatively look to the 2nd hand market, if your profits are good, then either the Banks or crowd sourcing should fit the bill.
I am still very cautious about businesses borrowing, where the profits are in the future, because new equipment is needed, if you are making a decent profit now keep hacking away until the loan is reduced, and the profits increase, then look to buying new kit and expanding from there.
