Hello... mahirap po bang makakuha ng business permit sa paranaque?

kse according sa website nila (http://www.paranaque.gov.ph) ito yun mga kelangan (single prop at rented yun akin):

1. Barangay Clearance
2. DTI (for single proprietorship)
3. Lease Contract (if rented)
4. Locational Clearance (4/F City Planning Office)
5. Occupancy Permit / Building Permit (2/F Building Official)
6. Fire Clearance (2/F BPLO Lounge)
7. Picture of establishment (inside & outside view)
8. Lessor's Permit

#4,5 & 6 each have their own requirements pa ata...Parang ang daming requirements! anyone care to share their experience? Pano po kaya ito mapapadali? Help please! Salamat po.
